Editorial Reviews

From Booklist

After visiting myriad places and eras in the first two volumes of this multiplatform, multivolume, multiauthor series, the three tweens Sera, Dak, and Riq find themselves starting this third book in 1850s Maryland. The coadventurers cross the path of the Underground Railroad, which has been taken over by the still mysteriously evil and not-yet-defeated SQ, and quite a bit of suspense ensues, especially considering the very personal elements introduced by Riq’s African American heritage. Although the quality of the dialogue continues to decline as the books roll on, the excitement actually builds well here, as does the increasingly satisfying combination of science, history, and fiction. The next title in the series is on its way this summer. Grades 4-6. --Andrew Medlar


Praise for Infinity Ring #1: A Mutiny in Time:"Tight plotting, snappy dialogue... the story moves at a breathless pace.” -- Rick Riordan, #1 New York Times bestselling author of Percy Jackson and the Olympians"'History is broken, and we need your help to fix it.' What kid could turn down an invitation like that?... It's a quick, straightforward adventure with a successful mix of action, adventure, and historical substance." -- Publishers Weekly"Save a place on your shelves for this fast-paced and fun series about historical time travel." -- Voice of Youth AdvocatesPraise for Infinity Ring #2: Divide and Conquer:"Many history-loving kids will be sucked in, while others will be hooked by the accompanying full-color poster-map... and corresponding online game." -- BooklistPraise for Infinity Ring #3: The Trap Door:"Three novels into the series, the Infinity Ring pulls off a shocking twist. This book earns the year's strangest compliment: It doesn't read like a time-travel story. It has all the usual tropes: impossible technology, split-second escapes, glimpses of the future. There's even an inventive variation on the grandfather paradox. But in its best scenes, it reads like a historical novel." -- Kirkus ReviewsPraise for Infinity Ring #4: Curse of the Ancients:"Fans of the series will already be hooked, but even more skeptical readers may be a little curious what happens next." -- Kirkus Reviews
