Merry Christmas!
To celebrate the festive season, we’re making Christmas in the Multiverse free for the next few days.

It’s the day before Christmas Eve, and every Santa in all the known universes has gone missing.
With the help of a very hungry reindeer and her Santa-lookalike partner Mike, Multiverse Investigator Alex Strand must travel to San TaClaus, stop an elf rebellion and free the Santas, real and fake, in time for Christmas.
Can she get to the Santas in time?
Will Schrödinger the quantum cat save the day?
Or will the elves mistake Alex as one of their own and force her to join their liberation army?
Find out in this tinsel-strewn, paper-snow-decorated festive mystery.
I hope you have a wonderful Christmas and don’t find yourself celebrating it in the wrong universe.
