Duke with Benefits by Manda Collins

This book picks up immediately after Ready, Set, Rogue. Lady Daphne Forsyth and Dalton Beauchamp, the Duke of Maitland, have been circling around each other. She is a genius at mathematics. She's also very wary because she's been burned by men before. First, her father who would use her to win money at cards. Then her tutor's son who... well... that's a bit of a spoiler but when he shows up, she's not happy.
Dalton is taken aback by this woman who says what she thinks and is willing to have sex with him without the sanctity of marriage. He knows that she's smart at math, but he also knows that he's a genius with people (we're told this over and over again.) Together, they are going to be able to not only solve the riddles his aunt left for them both, but discover the location of some long-lost gold.
Like the first book, this is a fast trip between introductions and Twu Lurv. We get a little more time since Daphne and Dalton met in the first book but that book didn't cover much time. We also got two characters who were nice enough but we got more "tell" than "show" in character development.
