8th/9th & up. 
 Seventeen is when everything changes. It can be a time to rebel, to experiment, to explore possibilities, and to experience everything that life has to offer. Unfortunately, for many girls it is also a time to disappear- and many of these lost girls are appearing to Lauren in an effort to be found. In dreams or visions or hallucinations, Lauren is haunted by more and more girls that call out to her to be rescued. Knowing that anyone she tells will think she's crazy, Lauren emotionally separates herself from those she loves and starts a lonely and dangerous journey to find the truth about the missing seventeen-year-olds that have reached out through time and space to seek her help. 
 With a bang-up premise, I was expecting to love this story, but I have to admit I felt a little let down. The narrative felt shadowy and unsubstantial- possibly appropriate given the topic, but hard to grasp and not as involving as I wanted it to be. Every time Suma started to grasp my attention, the plot began to wandering in circles, retreading familiar ground, leaving a lot to be desired given that this book is touted as a thriller. 
 While I never fully connected with the story, I do admit that with the last third of the novel (starting just before the "And Then" section) the author finally ramped up the action and partially redeemed and distinguished herself.
