InterWorld is a science fantasy book series cowritten by Neil Gaiman, Michael Reaves and Mallory Reaves.

Power of the Verse
InterWorld is a deceptively strong verse, adept in both magic and technology. It possesses peak human to low superhuman beings like Jakon and Neville, but the strongest beings are capable of destroying and creating multiple universes. Certain characters can absorb souls, and weapons like the Emitter can sever atomic bonds.
