Simmons, Dan. The Abominable (LittleBrown $28). Lovers of Simmons's blend of alternate history, mystery, and myth will appreciate this three-act thriller set in the interwar years. It's 1924 and the race to summit the world's highest mountain has been brought to a terrified pause by the shocking disappearance of George Mallory and Sandy Irvine high on the shoulder of Mt. Everest. By the following year, three climbers--a British poet and veteran of the Great War, a young French Chamonix guide, and an idealistic young American--find a way to take their shot at the top. They arrange funding from the grieving Lady Bromley, whose son also disappeared on Mt. Everest in 1924. Young Bromley must be dead, but his mother refuses to believe it and pays the trio to bring him home. Deep in Tibet and high on Everest, the three climbers--joined by the missing boy's female cousin --find themselves being pursued through the night by someone… or something. This nightmare becomes a matter of life and death at 28,000 feet. What is pursuing them? And what is the truth behind the 1924 disappearances on Everest? As they fight their way to the top of the world, the friends uncover a secret far more abominable than any mythical creature could ever be. "Amid the wash of detail, Simmons plants crucial facts and conjectures about early-20th-century Europe that won't pay off until Jake and his party are nearing the top of the world. Can murder and carnage be fully explained by the evil of men? Is a supernatural threat looming over the expedition? As usual, Simmons doesn't answer all the questions he's raised when the mysteries surrounding the loss of Percy Bromley are resolved, but his fans, like Jake, are sure to enjoy the journey."—PW.
