Joey Harper, almost 17, survived the fight from The Silver Dream (2013) and has been flung back to his world and time. Now he's off to find new recruit Josephine and battle evil Lord Dogknife and Lady Indigo to save InterWorld. Skirmishes are won as he and Josephine attempt to recover and search for other survivors. Because there is little carryover from the second book or much backstory, readers are left to make sense of the fast-paced and exciting but disjointed events. Supposedly the last in the InterWorld series, this is nevertheless open-ended. Series fans are the best audience here.

Gr 7 Up-This terrific sci-fi novel that combines an action-packed plot with thought-provoking themes immediately follows the events of The Silver Dream (HarperCollins, 2013). Lord Dogknife has left Joey Harker on his home Earth, broken, defeated, and alone. Joey's ally, the Time Agent Acacia, is lost in time, and the rest of the Walkers of InterWorld (freedom fighters) are scattered or pursued by Lord Dogknife and other magical beings. Hex and the techs of Binary have laid aside their age-old enmity to create and launch FrostNight, a terrible weapon that is designed to eradicate all planes of the Multiverse. Before their defeat, Joey and Acacia managed to interfere with FrostNight but to what effect is unknown. With the help of his curious companion, the multidimensional lifeform Hue, Joey must set about gathering a new corps of Walkers to form the nucleus of a new InterWorld in order to stop FrostNight, Lord Dogknife, and Binary's Professor from upsetting the multiple Earth's science-magic balance. The authors have created an indomitable hero in Joey, a young man willing to fight beyond hope to save not only his home, but all of multifaceted existence as well. The trio's writing is full of deep emotion, exciting action, and lush description. They've also given readers an interesting portrait of diversity in that all Walkers, whether they be male or female, centaur, or wolfling, are all versions of Joey from various Earths. VERDICT Gaiman, Reaves, and Reaves offer up a triumphant conclusion to the "Interworld" trilogy with this dynamic story. Eric Norton, McMillan Memorial Library, Wisconsin Rapids, WI

In this satisfying conclusion to the mesmerizing Interworld series, readers will find themselves feverishly rereading chapters in order to follow a compelling plot line. Joseph Harker must figure out how to save his earth and all of the metauniverses that have already been destroyed by Frostnight, the result of the merging of two opposite forces, the Binary and the Hex. He finds himself on a destroyed beta-InterWorld ship, with an army of his para-incarnations on a mission to get it running to save his earth. This is no easy task, but Joey forges on since there is no other conceivable alternative.Mind blowing is the best description for the situations that Harker must escape. The multiverse is beautiful, and the nightmarish characters from the evil competing forces are beautiful, dark, and mysteriously written, in a style that will conjure images that will linger in the reader's thoughts. The proliferation of characters, however, is confusing, to say the least. No sooner does one J-named Joey para-incarnation crop up than another shifts focus. It is recommended that readers take notes as they follow along. That being said, the conclusion of this trilogy will not disappoint InterWorld fans. It will keep them sucked in until the very end.Victoria Vogel.
