CURSE OF THE ANCIENTS

Armageddon isn’t all bad.

When the world ends, there will be earthquakes and tornadoes. There will be sheets of acid rain. There will be fires and floods and bolts of electricity surging out of the sun. That’s the first three pages of this fourth entry in the Infinity Ring series. No one will accuse the author of holding back. R.E.M. fans may wonder if the book is adapted from “It’s the End of the World as We Know It (And I Feel Fine).” But it turns out that an apocalypse was exactly what this series needed. As Sera uses the Infinity Ring to jump back and forth in time, from the end of the world to the age of the Maya, the story gains a sense of urgency that was missing from previous volumes. She has to prevent the Cataclysm, and her friend Riq may wink out of existence altogether. A time paradox means that his parents may never have met. These are the dangers of time travel. Like the previous volumes, this book suffers from terrible dialogue and implausible plot twists, but it also includes the funniest line in the series, a joke about TriSQuit crackers. (You had to be there.)

Fans of the series will already be hooked, but even more skeptical readers may be a little curious what happens next
