If you could have the ability to know exactly when any given person would die, would you choose to obtain this knowledge? 
 Maddie Fynn has never really had a choice. Since she was a young child, she has had an eerie ability to see, both in person and in photograph, the date on which both strangers and loved ones would ultimately meet their demise. It wasn't until the mysterious numbers on her father's forehead coincided with the day that he died in the line of duty that Maddie realized the true extent of the blessing ... or curse ... that she could never quite escape. 
 When her alcoholic mother learns she can make a buck off her daughter's special talents, Maddie is put to work reading death dates for her clients in exchange for the money that always seems to be pooled back into her mother's addiction. And, on that one disturbing day, on which a young mother comes to Maddie for help in making a critical decision regarding the life of her children, Maddie realizes just how much trauma and trouble can result from her ability to foresee what she should probably never know. 
 Soon, Maddie finds herself in dire legal trouble when the child of one of her clients is horrifically murdered. And when a second tragedy occurs in close proximity to the last -- again, related to the mysterious death dates, Maddie and her best friend find themselves as the primary suspects in the case of what seems to be a serial killing spree. 
 Can Maddie get to the bottom of these crimes before she faces a life sentence? Or, are there more dangerous consequences from knowing WHEN than Maddie could have ever imagined?

 I was pleasantly surprised by how page-turningly fantastic and fun this novel turned out to be. Laurie included plenty of unexpected twists and turns that really kept me guessing until the last few chapters -- even when I was previously confident that I knew how the story would end. 
 Beyond the thrill and action of the plot points themselves, I particularly loved the sensitivity and depth of the characters, who were understandably flawed and relatable, even throughout their extraordinary situations. And, while I found myself wishing for a sequel or a series to continue Maddie's story, I definitely changed my mind by the last page, totally satisfied by the sweet and fitting ending that really closed the story better than I would have imagined. 
 As an aside, I wondered through the whole story whether Maddie could see her own death date, either in a mirror or in a photograph, so I'm glad this was actually answered at the very end of the novel. 
 Sure, WHEN isn't War and Peace, but it's definitely an entertaining and engaging read that will likely appeal to a huge range of young adult fans -- or even just to readers in general who want a fun little escape. 
 (I did receive a copy of WHEN from the publisher, for the purpose of providing an honest review. That said, I actually ended up purchasing my own copy, which I hope will speak to the fact that I genuinely enjoyed this story!)
