Summary: Krista Carmichael is on a mission: to catch the man who kidnapped and killed her sister. When other young women are stalked and kidnapped in the area, the cops are led to GrapeVyne, a social network where the girls left detailed "thought bubbles" about their day. Ryan, the CEO of GrapeVyne, joins Krista on the search for the killer and online predator.
My thoughts: This book is great! In addition to the plot about Krista and Ryan finding the murderer, there are also several intriguing subplots: social networks and what information people, teenagers in particular, put out for anyone to see; the grief of a father who has lost his wife and now his daughter; Krista's mission work in a low-income area; and the corruption of GrapeVyne's partners.
