1.) To All the Boys I've Loved Before by Jenny Han-
I'm not the biggest fan of contemporary, but I will say that most contemporaries remind me of a warm sunny day and a trip to the pool. This book captures the drama of a teenage love triangle, which is good for pool-side reading. . . right? Plus, Jenny Han is like a magical fairy when it comes to writing a good dramatic novel.
2.) Gulliver's Travels by Jonathan Swift- As one of my personal favorite classics, I think I would recommend this one to anyone at any time of year. Still, its sense of adventure especially reminds me of the summery months. I love Swift's intricate character building (like the Lilliputions)!
3.) Nancy Drew and the Secret of the Old Clock by Carolyn Keene- Although this doesn't necessarily make me feel relaxed, it does make me feel nostalgic. Nancy Drew is all I read as a child, and even if I hadn't, I would still recommend reading Nancy Drew by the pool. They're quick and easy and NEVER disappoint. Sleuthing always does bring out my curious side!
