I won this book through a Goodreads giveaway by the author. 
 In Olivia and Jazz, Walsh has created a pair of sisters that perfectly represent the archetypes of just about any sibling rivalry, and yet they are utterly unique. I quickly and easily fell in love with winsome Olivia. She's such a free spirit, so innocently wise. I was fascinated by her synesthesia and the various and distinctive effects the condition has on everyone in her life. 
 Mystery, lovable fey reading, and so much more.
