Book number three of a four book paranormal romance dark fantasy series. I read the well printed and well bound MMPB published by Ace in 2011 that I bought new on Amazon recently.  Note that “Ilona Andrews” is the pseudonym for a husband and wife writing team.  I have purchased the successor book and will read them soon.
"The Edge lies between worlds, on the border between the Broken, where people shop at Wal-Mart and magic is a fairy tale—and the Weird, where blueblood aristocrats rule, changelings roam, and the strength of your magic can change your destiny..."
Audrey Callahan has lived in the Edge all of her life.  She is an excellent thief and lock breaker.  But her family lives off thieving exclusively and she wants to have nothing to do with it.  Especially when her junkie brother sold her to his drug dealer.
Kaldar Mar is one of the surviving members of the Mar family from their previous encounter with the Hand, the horrible secret service of magic users from the Duchy of Louisiana.  Kaldar now works for the Mirror, the secret service of magic users for Adrianglia.  And he has been given an assignment to retrieve a pair of magic bracelets that can store magical energy for the user.   But he needs help and Audrey is not a willing partner, plus the two young men who have stowed away on his 120+ foot long winged wyvern.
