Christina was the one who explained what the term, “heat” meant. Just like actual regular wolves, werewolves have cycles of heat, in which they have a strong desire to mate.
This usually happens only with female werewolves. Unlike wolves’ heat cycle which occurs once a year during winter, werewolves’ heat cycle occurs to those who found their mate but were unable to complete their mating process. The mating process includes the male having intercourse with his mate and biting their mate in the neck.
The point of the bite was to mark that that werewolf was taken and for the heat cycle not to happen again in the future. The ones who are affected by the scent of heat of the female are unmated werewolves and their mate. Family or mated werewolves are not affected at all. 
Ryder Point of view Shit, shit, shit. I pressed myself on the wall trying to gain control over myself. Take her, take her, take her. Complete the mating bond. Hold her, kiss her, make her yours. I groaned and pressed both my hands on my head. Shut up, shut up, shut up, shut up! Come on, Ryder. Control yourself. The timing of her heat cycle was bad. She doesn’t have her memories and has no idea what heat cycle even was. She must be scared right now. I was at the back of the hospital, trying to gain control over my wolf. She was in heat. I could smell it on her. Dammit, I can still smell it all the way here. I shut my eyes tight when I felt my eyes turning black. Breathe Ryder, breathe. "Ryd
Ryder Point of view Take her. I gripped the steering wheel. Make her yours. Breathe Ryder, breathe. I slowed down a bit to avoid any accidents. I came to a stop and parked by the sidewalk. I rested my head on the steering wheel and breathed through the urge to go back. I can’t go back to her in the state she is right now. It isn’t right. It would be the same as taking advantage of her just because I was aroused by her smell. I let out a hard sigh. If I were to come back, she has no control over herself. If we mate when she isn’t in the right mind, she might regret it the next day. She would hate me. I started hearing people outside the
Samantha Point of View My eyes feel heavy. I felt so bare. I can even feel my head aching almost as if I drank the whole night. I opened my eyes slowly. Adjusting my eyes to the light. It was a blur and I felt cold. Actually cold is not the word for it. I felt bare. My eyes literally popped open as I realized I am naked under the sheets. Oh my God, what happened last night. I bit my lip. What do you think happened last night? There are clothes on the floor, my bed is somehow a mess and so are my things on the table. The most obvious part is that I am naked on my bed. Oh my god.. Did we... I covered my face with my hands as I felt the heat rising up to my face. Crap, we did. And I don't remember any of it. Maybe that's fine. Right? Stupid, it is fine! Don't
Xavier Point of view I put the phone down and frustratingly sighed. Something was coming and we had no idea what was going on. I got up and changed into my regular clothes and started packing up my stuff. Christina comes in with a glass of water then frowns when she sees me packing up my stuff. “What are you doing?” "Packing my stuff.” Christina gave me the look. “I am fine.” “You said that last time, remember? When you went to that building with Ryder where Sam was. You collapse." Christina said in a worried voice. She sat down and held my hand. "I saw what Sam and Ryder went through without each other. I don't want to feel that way too. I don't want to lose you." I let my other hand rest on hers and my forehead touched hers. "I'm so
Riley Point of view *Flashback* "Samira," I caught the ball in my hand. It was just Ryder and me on the basketball court. This is usually where we meet up but the other two were held up by the teacher. "Who's Samira? Is that code name for Samantha?" "No, it's not. It just sounds familiar." Ryder said as I threw the ball back at him and he easily caught it. "And I told you I can't play basketball that well. I'm a football kind of type." "You're athletic and all you have to do is to throw a ball in the hoop." Ryder made a face. I laughed. “Come on. Practice makes perfect.” "I miss every time," he says. Probably because he wasn't trying. He just doesn’t know how to angle it right but when it comes
Xavier Point of view "Knock knock! Knock knock!" That wasn’t a knock nor someone talking. It was a ringtone coming from my phone. I didn’t remember changing my ringtone. Christina and I parted. The ringtone of my phone was changed into someone yelling knock knock in every annoying way as possible. I raised my eyebrow and looked at Christina for an explanation because she was the only person I told my new password to. She gave me a sheepish smile and laughed. "I was bored and your phone was the only thing here." I shook my head and chuckled as I reached for my phone. That ringtone reminded me of my birthday. *flashback on the morning of Xavier's birthday* "Knock knock! Knock knock!" I cursed out loud for that annoyin
Linda Point of view (when she came to Sam’s house) "I'm happy," I finally get to see Sam back home safe with Ryder. Even Ryder. He looks more relaxed when she is around. "I get to see them like this. How they used to be, you know. Calm and peaceful." *Flashback* (a few days after Sam was kidnapped) "Where is Ryder?" I asked. Riley and Christina looked at each other and then looked outside. We were in a car, driving towards Ryder’s house to see how he was doing and try to help him out. "He hasn't left the house. He's been calling the other packs for help but no one has seen or heard from her. Th
Lily Point of view I felt my heart beating back alive. Those years I have been trapped in that prison, felt like I was dead for years. It was like my own personal frozen hell. breathed in the fresh air that I so missed. I let the wind blow my hair away and I waited for my brothers to catch up. "You are pretty fast Lil' sis," Liam finally arrived and bent down to catch his breath. His twin brother followed behind him, out of breath, and chuckled at Liam. "Damn. She beat us, bro." I smiled as I studied their familiar faces. The joy rising up to my eyes as they began to tear up over the joy of having my family back. I miss them so much. We left Sam's pack territory because we felt the pack members being a bit uneasy and scared of having vampires
