Revenant

Forgotten Heroes #4

by M.R. Forbes

The game is over. The real war is about to begin.

Hayden and Caleb face their greatest challenge building an alliance across the multiverse itself. Different timelines. Different realities. Different versions of friends and enemies alike.

But assembling an army is only the first step. The true enemy has existed since before humanity crawled from the primordial ooze—and they don't intend to fall without a fight.

The Relyeh have ruled the multiverse for eons.

It's time someone challenged their reign.

[Calvin · Rating 5 out of 5]

The Beginning of the End

Not a whole lot of action in this book, but that's to be expected. It's basically just gathering allies from all of the other Forbes series. For long time fans, you'll recognize the names, for newer readers you'll have a lot of catching up to do.

[Sue Ricketts · Rating 5 out of 5]

Another romp with Hayden and Caleb. Surprise! it's not the final chapter. We get to meet them in the next book as they continue to aim to get rid of the two most powerful immortals in the multivers.e.

good set up for the finally

Ties all the forgotten universe books, and even some extra books together. Sets up the final book nicely. Can’t wait to see how it ends end.
