I was so excited at the concept of this book. Puerto Rico + magical realism in a YA novel? Sign me up! 
 ...Color me disappointed. 
 My main issues: 
 - Puerto Rico was depicted as one big stereotype of itself (complete with sexy Latin lovers). The Spanglish felt "off", and was clearly written by an outsider - was it that hard to run it past someone who hears this stuff on a regular basis? 
 - The island is basically a colorful backdrop for the stories of two white American characters. (view spoiler)[(Technically, one is revealed to be half-Dominican, but he's a blond-haired American who seems to identify as white.) (hide spoiler)] Puerto Ricans themselves only seem to play the role of servants or redshirts. 
 - While reading this, I scribbled out an entire page of fact-checks, including: the Taino language went extinct in the 19th century; Puerto Rico is simultaneously its own nation AND part of America; your average Puerto Rican isn't necessarily listening to salsa on a daily basis; Puerto Ricans are not always a socioeconomic underclass (especially on their own damn island). 
 - The main character didn't feel like a real person, and his motives didn't make sense to me. He seemed mainly driven by... ennui?
