Hubert in Heaven [EPUB ebook] 

Is there a place in heaven for an accidental angel?

A hologram in a video game, Hubert is accidentally transported to Heaven, where he must stay until he finds his purpose. As an aspiring angel, he must perform many Heavenly tasks which he attempts to automate with his personal computer — to disastrously delightful results.

Only when he learns to “be still — and let God do His work” does Hubert restore Heaven to perfect order, and this hi-tech angel finally gets his wings.
