Readers who haven't read the previous volume, I'll Be There, may spend about the first third of this book a bit confused. Author Holly Goldberg Sloan's third-person omniscient voice goes into the heads of the characters to bring the reader up to speed on their situation, often in plodding, angsty prose that mirrors the character's states of mind, as in this passage:
"He was hers.
"Weren't she and Sam one?
"Hadn't they already been tested?
"Since the impossibly sexy Destiny had appeared, suddenly they were one plus the shadow of someone else. And it felt like they were three.
"Was she imagining that?
"It was real."
Sam, Riddle, and their evil father are compelling, complex characters; many of the others are essentially ciphers or personifications of qualities needed to move the plot along. But once the action starts, very little of this matters; more sophisticated readers may roll their eyes a bit, but even they will be turning the pages fast to see whether the heroes can survive.
