Stand-in wife

the long version

"Playing with dynamite, a girl could get burned ... What does he know about love and marriage? And exactly how did he, Ross Coltrane--a special forces elite soldier and demolitions expert--end up playing middleman to his kid brother and the estranged wife? And most important, why is he suddenly noticing how beautiful his sister-in-law is? He's never thought about his brother's wife ... that way ... before. Then he figures it out and everything makes sense. This tantalizing woman is the other twin! The identical sisters have pulled a swap and duped everyone around them. Furious much? Oh, yeah. Poised to bring down their plan, Ross hesitates. Something about Vivienne Jansen's courage and zest for life gets to him. Except, he's not a man who has feelings. Everyone calls him the Iceman. He doesn't know how to be anything else"--Publisher.
