Okay, I just finished the latest one last night. I've been keeping up with the series since middle school, so this is always the first thing I look for. The short answer is yes, but it's more about expansion than a whole new crew. Richard Paul Evans tends to do this thing where he deepens the existing world rather than resetting it.
There's a new Glitch, a teenager with this ability to generate intense localized EMP bursts that fry electronics. He's not a full-on villain but more of a conflicted asset being fought over by both sides. His introduction really amps up the tactical stakes because the Electroclan can't just rely on their powers around him; they have to get creative. Honestly, he felt like a natural extension of the existing power system.
The other significant addition is a scientist working for the resistance. She’s less of a field character and more of an info-dump/exposition role, explaining some new lore about the source of the Glitches' powers. It fills in some gaps but didn't feel as organic as the new Electroclan members did back in the day. So, new faces? Sure. Game-changers? The Glitch kid maybe, but the overall dynamic still centers on Michael, Taylor, and Ostin.
