Past and present converge in Las Vegas and ghost town Indigo, Nev., the site of a long-ago gunfight, in this engrossing paranormal romance from bestseller Graham (The Death Dealer
). Just as Jessy Sparhawk, who's part Lakota Sioux, wins a bundle playing craps at the Vegas Sun, Tanner Green, a bodyguard for the owner of the casino where Jessy works as an entertainer, falls dead on top of her with a knife in his back. Dillon Wolf, a local PI who's part Paiute, and LVPD homicide detective Jerry Cheever soon have a second victim on their hands when a hit-and-run driver kills a Sun parking lot attendant who saw Tanner get out of a limo shortly before he collapsed on Jessy. Jessy and Dillon, both of whom are nightwalkers who can communicate with ghosts, must love and protect each other as another violent showdown approaches in Indigo. Graham's dependable romantic flourishes enhance this bewitching blend of Native American lore, ghostly shenanigans and modern-day chicanery. (Apr.)
