The mask
(Book)

Series information from Fantastic Fiction.

Vanessa Michael Munroe, chameleon and information hunter, has a reputation for getting things done dangerous--and not quite legal things that have taken her undercover into some of the world's most deadly places. Still healing from a gone wrong hijacking off the Somali coast and a brutal attack that left her near death, Munroe accepts an invitation from her lover, Miles Bradford, to join him in Japan where he's working as a security consultant protecting high-value technology from industrial espionage. In the domesticity of their routine Munroe finds long sought after peace, until Bradford is arrested for a murder he didn't commit and the special interests who've set him up come after her, too.
