Finders Keepers by Russ Colchamiro is most definitely a fun read.
A pair of cosmic engineers, responsible for constructing The Earth, have misplaced a jar of Cosmic Building Material, essentially, the universe’s DNA. And with the inventory due to be taken, they need to get it back quickly or face the ultimate punishment.
Meanwhile on Earth, a pair of young backpackers are travelling across Europe, looking for someone who can tell them about a mysterious jar found in a cave in New Zealand, unaware that others, exiled from Eternity, will stop at nothing to take it from them.
It’s a entertaining story, broken into small chunks which can be read as time allows (helpful if you find it difficult to carve out an hour or two at a time). Even the minor characters are fleshed out enough to make them part of the story instead of props. And as the story wraps up with some surprising twists, even the most villainous of the characters begins to show signs of redemption.
