Out of all the books, I suggest To All the Boys I've Loved Before. I've read a few others on the list like Don't Look Back (which was a pretty good novel), and My Life with the Walter Boys (I've only ever read the Wattpad version, before the author ever had anything published). They are both fantastic books that I would recommend to many people, but out of all of them... To All the Boys I've Ever Loved Before by Jenny Han has to be my favorite. If it doesn't make it to top five I'll be very disappointed. It's a must read for young teenage girls; Giving them advice on life, without being boring and feeling like a lecture. It's an excellent balance between excitement and the giddy-nervousness that girls get when liking a boy(s), and frustration when author, and characters, leave you wanting more.
