Following Ten Thousand Skies Above You, the stakes have never been higher for Marguerite as she races through parallel dimensions to stop the evil organization Triad and her most dangerous opponent yet--an alternate version of herself who is determined to kill every Marguerite who opposes her. The gripping plot gains nuance from the thoughtful explorations of self-determination and destiny.

In the last volume of Gray's multiverse-spanning romantic-thriller series, Marguerite must work quickly to stop her evil counterpart from destroying the parallel universes in which other versions of herself exist. At the same time, she needs to try to convince her true love, Paul, that his fractured soul is not too broken to love. The action is nonstop and the characters and settings are almost overwhelming, but devoted fans will enjoy discovering new worlds and finding out what measures Marguerite will have to take to stop the destruction of the multiverse. A satisfying, if chaotic, end to the trilogy.

Gr 9 Up-n the thrilling conclusion to the trilogy, Marguerite Caine is in the middle of a cross-dimensional fight to save multiple universes from extinction. With the Firebird device that her parents created, Marguerite can travel among universes. However, she is becoming aware of the impact that traveling has on each dimensionand on herself. In a culmination of events begun in the previous volumes, Marguerite has discovered the evil plans of the Triad Corporation and is trying to catch those involved before destruction occurs. Paul, Marguerite's friend and love interest, has changed since his soul split in four, and he struggles with his dark side, pushing Marguerite away while also trying to assist her across the multiverse. With fast-paced action that starts from the first chapter, this title will draw readers into an enthralling chase across time and space. The plot cleverly connects many universes with multiple dimensions of personality, and the characters are intriguing, smart, layered, and independent. Although this offering can be read as a stand-alone, those who haven't read the first two novels will lack important context. VERDICT Sci-fi fans are the obvious audience for this, but readers of all genres will enjoy the nonstop action and unique story.Melissa Poole, Clemson University Library, Anderson, SC
