Two young teens with special powers face an ancient evil rising from the very heart of the Tinvali Empire in this doorstopping series opener.

Pursued by ruthless agents eager to exploit her mysterious ability to read peoples’ true feelings, Arden—eventually, after many chapters alternating between dual narrators—links up with foundling Mako, a budding music mage who’s carefully hiding the fact that he’s invited an invisible smooth-talking trickster spirit named Narrix to be his lifelong guardian. It seems that some of Narrix’s fellow spirits may be even nastier—and there are ominous hints that they might be sneaking back into the world. Several of Arden’s adventures do more to bulk up the page count than advance the plot in any meaningful way, and though (like many of Mull’s protagonists) she’s a dab hand at snarky banter, she otherwise comes off as a rather wooden character. Readers may find Mako’s journey and conflicts more absorbing, as he struggles to balance the joy of blossoming into an outstanding warrior under Narrix’s tutelage with the sneaking suspicion he’s made a bad choice of tutor. Whether his concerns are valid or not remains to be seen. The leads present white.

Ponderous and protracted, with more work needed on both the world and the characters.

(Fantasy. 10-13)
