Labyrinth of Lies by Irene Hannon

When the daughter of a high-profile businessman disappears from an exclusive girls' boarding school, police detective Cate Reilly is tapped for an undercover assignment. It doesn't take her long to realize that beneath the veneer of polish and wealth, things are not as they seem at Ivy Hill Academy. But the biggest surprise of all? The only man she ever loved is also working at the school.

Zeke Sloan has never forgotten Cate, but now isn't the best time for their paths to cross again. When their two seemingly disparate agendas begin to intertwine--and startling connections emerge among the players--the danger escalates significantly. But who is the mastermind behind the elaborate ruse? And how far will they go to protect their house of cards?

My review:  Cate is a women 33 years old.  She was tapped to go undercover at an all girls school to pose at a 17 year old teenager.  Her task is to find out all she can about a teen girl who disappeared from the school.  Cate didn't want to go undercover again.  But she was persuaded to go because she was the only one who could pass for a teenager.  She was told it would be an easy assignment.  Wrong.  She gets there and almost immediately runs into an old boyfriend who left her for an undercover assignment with the DEA.  She's never recovered from the heart break.  The deeper she digs the more dangerous this assignment becomes.  She finds out that the teens disappearance is connected to Zeke's undercover job at the school.  The ending was surprising as I never guessed who the culprit was.  

I recommend this book to all mystery readers.  I was given this book by Revell Publishing via NetGalley in exchange for an honest review.  I was not compensated in any way.
