Will Adrian and Liam risk it all to embrace what’s between them? Or will their own insecurities and the pressures of college life keep them apart? A slow-burn college romance filled with longing, tension, and the sweetest of lessons—the kind that only love can teach.

Before the dark, obsessive, hideous, and disabled Alpha of the Wolf Pack chose his wife, rumors spread that he favored Cat Clan beastwomen above all others. My fiance feared that my family's maid would be selected, so he spent days and nights making passionate love to her in my bed behind my back. Only after the maid conceived his beast egg did he finally feel at ease. On the day my fiance and I were supposed to form our bond, the maid stroked her slightly rounded belly and flaunted it before me. "Ms. Sinclair's bed certainly served its purpose. Nate and I only needed three months to conceive a beast egg." After speaking, she deliberately covered her mouth with a triumphant smile. "Oh, I forgot to mention—Nate is actually the exiled heir of the Eagle Clan! "For old times' sake, he said he'd graciously allow you to join the Fairfaxes as my maid to care for me during my pregnancy." I let out a cold laugh. She was destined for disappointment. If she would not marry the Alpha of the Wolf Pack, then I would. I could never be her maid, because I would only ever be the Wolf Pack's Luna.
