Pel brown lives a normal suburban life, with a wife and daughter, never suspecting that there's more to the universe than the mundane existence he's used to. That changes when a strange gnome like creature steps through his basement wall, telling Pel it's from a different world and looking for help. As strange an event as that was, Pel chalks it up to a possible hallucination...until he gets another visitor from his basement wall, this time a normal looking man, but dressed in archaic clothes and carrying a sword.
As Pel tries to make sense of this, across down a spaceship appears out of thin air, and immediately plummets into Amy's backyard. She is half afraid and half curious, but relieved when a squad of blonde men exit and is torn between her curiosity and being upset with their trespassing.
Soon Pel and Amy and their respective other worldly visitors meet up, and learn that each visitor is from a different world other than earth, one based on magic and the other on high tech science, neither of which work on Earth. After consulting with their respective lawyers, and talking to each group, they decide to play out the strange stories, despite tales of an evil force both groups are fighting. Pel and Amy still feel they can't quite figure out the marketing angle for some new sci-fi show, and decide to push to find out for themselves.
After returning through the portal in Pel's basement, things suddenly take a turn from whimsical fantasy lark to a harsh reality of violence across multiple dimensions, with a handful of Earthlings caught along in the flow. Pel and Amy and their friends and family try to survive while applying logical Earth sensibilities to strange worlds.
Watt-evans applies his typical rational protagonists into what turns out to be a much darker fantasic world than his more common light hearted fare. It's a great change from his standard, while still keeping much of his normal style and tone. Very interested to see where the rest of the series goes.
