Allusion

Book excerpt: Every year, an anonymous gift is left on eighteen-year-old Lucy's porch. It's the only gift she receives all year, and it's exactly what she needs. This year's gift exposes hidden clues, untangling the undisclosed fates of her parents. Along the way, she finds Toph, a college athlete who's easy on the eyes and deems to be more useful than suspected. With the help of her best friend Art, a chemistry genius who resides at the nursing home where she's employed, she delves into an impossible mission for truth, love, and freedom.
