Between this and Anna and the French Kiss, Stephanie Perkins has proved herself as the master of slow-burn YA romance. This book kept me up until like 2am as the insane sexual tension builds and builds and I can't stop reading until they JUST KISS ALREADY. (And, sometime after 2am, they did, and it was sublime) 
 I hugged this book when I finished it. Bring on Isla and the Happily Ever After!
