New Adult: The Bet by Rachel van Dyken
This book is #1 on the New York Times bestseller list, and rightly so. My review will go online soon, but if I were you, I wouldn't wait for that. Just go read it! It's amazing.
Chick lit: The Trouble With Paradise by Jill Shalvis
A great book to take with you to the beach. I read it during the winter, but this book makes you long for the summer, believe me.
Paranormal Romance: Pleasure Unbound by Larissa Ione
This series has the perfect blend of main characters, it has all the paranormal beings you could wish for; vampires, werewolves and incubi. I enjoyed it very much!
Young Adult: Avalon High by Meg Cabot
Normally I'm not really into Merlin and King Arthur stuff, but this book was so fun to read that I gave it five stars. It's been awhile since I read it, but I remember being very sad that it was a stand alone book.
