Secrets in the Stacks by Lynn Cahoon

Book shop owner Rarity Cole got a second chance at life, unfortunately not everyone is so lucky… after a body is found and an ominous Tarot reading spells disaster she must keep her friend safe from a killer—even if the cards are stacked against her in a mystery readers of Richard Osman and Ellery Adams will devour!
Following her recovery from breast cancer, Rarity has embraced a life of healing and service in her Sedona, Arizona, community. She welcomes the opportunity to participate in the annual summer healing fair with her fittingly named new-age bookstore, The Next Chapter. The members of the Tuesday Night Survivors’ Book Club are also volunteering, maintaining a cooling station for overheated festivalgoers, and hosting a Tarot card reader for entertainment.
But one member, Darby, is anything but entertained when the Tarot reader pulls a Death card. With a mammogram coming up, she’s freaked out and goes home—only to walk into a crime scene where someone near and dear to her has been murdered. Despite the objections of Detective Drew Anderson, Rarity is determined to help her friend and protect her from being the killer’s next victim . . .
