If you're dipping your toes into the world of PG-13 romance, I'd start with 'To All the Boys I’ve Loved Before' by Jenny Han. It’s lighthearted, sweet, and has this cozy vibe that makes it perfect for beginners. The story follows Lara Jean, a high schooler whose secret love letters get mailed out accidentally—cue the chaos! It’s got just the right blend of awkwardness and heart-fluttering moments without anything too intense.
Another gem is 'The Sun Is Also a Star' by Nicola Yoon. It’s more poetic and introspective, following two teens over a single day in New York City. The romance feels urgent yet tender, and it explores deeper themes like fate and family, which adds layers without overwhelming new readers. Plus, the alternating perspectives keep things fresh.
