Macky's recent inauguration into the CCC brings waves of excitement to her and to everyone she knows. And with Christmas around the corner, the young sleuth can't help feeling cheerful. But the happiness screeches to a halt when a car chase leads to a surprising discovery: Kai is the target of a vicious cold-blooded killer. But Macky also has troubles of her own. She's sure people she has known and trusted her whole life are keeping secrets from her, ones that will send the world crashing down. But with a man on the loose who will not rest until he sees Kai's gravestone, secrets will have to wait as the fight for Kai's life. But . . . what is Kai hiding? Throughout a hostage crisis with a threat to destroy one of San Francisco's most well known sights, a constant bombardment of attacks on a CCC member Macky loves dearly, and a fight between Kai and her cousin that will bring the two to each others' throats, can Macky and the rest of the CCC stop this merciless man before he gets what he wants: a city full of corpses with Kai's among them? - - -
