Buried Secrets by Leighann Dobbs
I really enjoy the Blackmoore Sisters Mysteries. In Buried Secrets, they head West on a treasure hunting trip with Luke, one of the sisters' boyfriends and his team. I like that the people around the women recognize, and believe in, their powers.
I wasn't sure how I'd feel about the sisters leaving their hometown, but since they took all of the recurring characters with them, it didn't really matter much. The girls piece together what happened Dead Water's past and get right in the middle of some present day illegal activities. Overall, it's a bit predictable, but there was a least one twist I didn't see coming.
I would suggest starting the series at the beginning. They're light, quick read that are just fun. There are a lot of characters though, and a variety of powers, so I think starting with #1 allows you to get introduced to them all and get to know them.
I'm looking forward to the next in the...
