The Bad Guys come on strong in this sequel to The Door to Time (Jan. 2006), as young Jason and Rick race malign adult rival Oblivia Newton through the ancient city of Punt to solve clues leading to a mysterious map hidden in a labyrinthine library. Meanwhile, back in the present, Jason’s twin, Julia, and the enigmatic old caretaker Nestor are attacked by Oblivia’s vicious henchman Manfred under cover of a wild storm. As before, the focus is more on keeping the plot rolling than on attending to logic or historical detail, but along with the evocative assemblages of cryptic documents and drawings heading each chapter, there’s enough atmosphere, action, suspense, as-yet-unsolved mysteries and sharp-tongued repartee to carry the tale over rough spots. By the end, Oblivia’s on the verge of total triumph; let’s hope for better news in the next episode. (Fantasy. 10-12)
