" -- Booklist Praise 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 Reviews Praise 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.
