After Shard's sacrifice, the whole team of Battle Force 5 fell apart. They began to fight for only themselves. They split apart. Agura was the only one that stayed with Vert who has to go through this hard time with no one but her. Zoom hasn't been seen for so long, and many people say that he went somewhere, but never came back. Sherman and Spinner try to find a way to pass the time without their little sister there, trying to find a possibility that she's still out there. But what happens when the hubs computers pick up something. A beacon, calling throughout the multiverse. Someone that's trying to find their own way home. Vert has to pull himself and the team together long enough to figure out who is on the other side. And what they find, could surprise them all.
But then Doom, the warrior returned, and someone who owes Shard a HUGE debt shows up, and the mysterious person agrees to help them find Shard, and to help stop Doom... once and for all.
Suggest you read book one, Broken Battle to understand what is happening. I do not own Battle Force 5, just my own character, Shard (if she is alive, and just so you know, if she is, everyone else thinks she's dead. IF!!!) and @TwilightSage12 who owns Kala
