Janelle Ortega and Chuck Bender are drawn deep into a threatening web of hostility and deceit in Saguaro National Park in this page-turner of a mystery.

“A winning blend of archaeology and intrigue, Graham’s series turns our national parks into places of equal parts beauty, mystery, and danger.”
—EMILY LITTLEJOHN, author of Lost Lake

When Janelle Ortega’s cousin from Mexico is found brutally murdered at a remote petroglyph site in Saguaro National Park, she and her husband, archaeologist Chuck Bender, are drawn deep into a threatening web of hostility and deceit stretching south across the US-Mexico border and back in time a thousand years, to when the Hohokam people thrived in the Sonoran Desert.

Here’s the description of Standing Dead.

From critically acclaimed, master thriller author Margaret Mizushima, comes the eighth installment of the award-winning Timber Creek K-9 mysteries.

“Tense and satisfying,” (JA Jance) Standing Dead is the perfect read for fans of CJ Box and Longmire.

Deputy Mattie Cobb and her sister, Julia, travel to Mexico to visit their mother, but when they arrive, they discover that she and her husband have vanished without a trace. Back in Timber Creek, Mattie finds a chilling note on her front door telling her to look for “him” among the standing dead up in the high country.

The sheriff’s department springs into action and sends a team to the mountains, where Mattie’s K-9 partner, Robo, makes a grisly discovery—a body tied to a dead pine tree. Mattie is shocked when she realizes she knows the dead man. And then another note arrives, warning that Mattie’s mother is in desperate straits. In a last-ditch gambit, Mattie must go deep undercover into a killer’s lair to save her mother—or die trying.
