Broken Ice by Matt Goldman

P.I. Nils Shapiro and his partner, Anders Ellegaard, are hired by wealthy businessman, Roger Engstrom, to find his teenage daughter, Linnea. She went missing while in St. Paul to watch a hockey tournament. One of Linnea's classmates, Haley Housh, disappeared around the same time and was found dead in a local cave. Could their vanishings be connected, even though they weren't friends? In fact, Shapiro becomes even more determined to solve both cases when he is shot with an arrow while at the cave crime scene. In this second book in the Nils Shapiro series, Goldman writes a mystery that will appeal to fans of Robert Crais' Elvis Cole.
