Quinn Knight, a new sixth-grader at Hill Springs Middle School in Central Texas, has always been a little different. Not only is she an astrophotographer who battles chronic migraine headaches, she’s recently discovered that the stars—the Pleiades constellation, to be exact—are trying to tell her something. Someone is threatening Quinn’s older sister, eighth-grade social butterfly Vivica, and Quinn realizes the clever constellation is revealing the clues she needs to save her sister! But she can’t let anyone know she’s having cosmic conversations—making it in middle school is hard enough as it is—so Quinn keeps the secret message-sending stars under wraps. Soon, Quinn and her new friends, Tiya and Xavier, are hot on the trail of Vivica’s mysterious tormentor. But sometimes, there are more questions than answers written in the stars.
