edit data

Caleb Fast is the author of a growing collection of Science Fiction titles. His series The Battle for Allegra is his most popular by far, and is the focus of most of his efforts of late. His flagship series, The Limit of Infinity is still growing as well, as is its following. He enjoys writing on a range of science fiction subjects, and can't go too long without writing some sort of battle. However, Caleb does a lot more than writing. He also enjoys going on long hikes, long drives, and is a devout bookworm. In addition to all of that, Caleb runs his own antique bookstore and a few other gigs too.

Caleb currently resides in the Pacific Northwest, just outside of Portland, Oregon.

New Book Release!

Hi, folks!

Odds are that, if you're following me, you know that I lost an entire book. An entire, edited book.

You know how bad that hurt me.

But you also know that I didn't quit.

This was (and is) my favorite book to date, and I wasn't about to let it run wild in Unpublished Bookland. It was going to be tamed and brought to market! It was going to be shown off to the world!

So, that's what I did.
