When a meteorite falls near her campsite in the San Rafael Wilderness, troubled teen Leona Hewitt ventures down into the crater looking for a souvenir. What she discovers changes her life. Contained in the meteorite is a sticky, mucous-like fluid that bends light, cannot itself be seen, and seems to grow in the presence of living tissue. It’s drawn to her. But when a government team arrives in hazmat suits and cordons off the meteorite impact site, Leona questions her decision to take it home with her. For one thing, there are rumors of an extraterrestrial threat. For another, it has been speaking to her. It wants to be worn . . . stretched on like a second skin. It’s seeking out her weaknesses, exploiting her deepest fear—that the only boy she’s ever loved will unearth the vile secret in her past and see her as a monster. Now it promises salvation. It can make her invisible.
