The Mountain Master of Sha Tin — Ian Hamilton

In the latest installment of the Ava Lee novels, Ava becomes embroiled in a violent war between feuding gangs vying for control of the Wanchai territory in Hong Kong.

Ava is in Shanghai visiting her ailing friend, the Mountain Master Xu, when a triad war breaks out in Hong Kong. Sammy Wing, an old enemy of Ava's who has twice tried to kill her, has enlisted the aid of his nephew Carter -- the new Mountain Master of Sha Tin -- to reclaim control of his old territory, Wanchai, from Xu's men.

There is nothing subtle about the Wings' methods. Xu's most trusted enforcer, Lop, has been shot, and six of his street soldiers kidnapped. The Wings threaten to execute them unless Xu's men vacate Wanchai immediately. Ava steps in to broker a settlement, and the Wings respond by sending her a box containing six fingers -- and a twelve-hour deadline.

As the violence and tension mount, Ava is driven to the edge, and she is forced to devise a plan that will bring her face-to-face with Sammy and Carter Wing. The only question is who will pull the trigger first?
