Goodreads Summary

Mercedes is the main character and the main draw to this novel.  She is smart, brave, and charming.  Jack, the mystery solver, is just as smart, fairly charismatic, and inquisitive.  There are several other integral characters, each having their own quality or quirk that will make them stand out to the reader.  The story is told from several perspectives, making it easy for the reader to get the full picture and meet and follow the characters through the story. 

The story itself was a pleasure to read.  Science fiction fans will enjoy this novel too.  The very idea that a substance could be injected through a humans veins and then go on to control/attach to the humans thinking/feelings is unreal, but eerily intriguing.  The technical part of the book is handled well, the reader should not be confused.  There are a fair amount of action scenes, the author describes the events vividly and spares no detail.  In books containing any mystery, the reader needs to feel as if he/she understands the whole plot; with this book, the reader will find that satisfaction.  This book is recommended to adult readers.
