Pure fun!
I'll admit I was a bit skeptical at first - as other reviewers have noted, Izzy is not your typical chick-lit heroine (to put it mildly). But as the story progressed, she grew on me, and I thoroughly enjoyed her shenanigans and all the family drama the Alvarez clan brought to the table.
I loved how Izzy's adventure played out in the end - and now that I have seen glimpses of Pilar's HEA, I need to read her story, too!
