Sally Alder thought she'd left Laramie and outgrown her hard-drinking, guitar playing, hell-raising post for good. After all, this former singer known as Mustang Sally has become a respected history professor. What's more, she's been named to a richly endowed position at the University of Wyoming. But this plum job lands her back in Laramie - secretly researching the life of one of the town's most famous yet little-known citizens, the late Meg Dunwoodie.

Of course, everyone knows Sally's poking through old Meg's papers, and a lot of people think that buried among them is a treasure map that could lead to a fortune. Most of Laramie is determined to find it, including a bunch of clueless burglars, a curious sheriff, gossipy friends, and greedy faculty colleagues. And, as if that isn't enough to distract Sally, sexy Hawk Green is back to rekindle the romance she thought was gone forever.

As she delves into Meg's romantic past, Sally discovers the forces of good and evil in Laramie are beginning to align in a mysterious way. And if she doesn't learn from the post quickly enough, she may be doomed to repeat deadly mistakes.
