It's Groundhog Day, 1906. February 2nd is stuck on repeat, and only our intrepid trio appear to have noticed. Emmeline senses the meddling of a higher power - possibly her aunt. Reggie's sure it'll be the handiwork of the subterranean horror one least suspects. And Reeves considers it all "most disturbing." Can our heroes save the world from perpetual winter? And could ending the time loop be just the start of an even thornier problem?This short novel is the sixth Reeves & Worcester Steampunk mystery and is set a few months after The Unpleasantness at Baskerville Hall. "A fun blend of P.G. Wodehouse, steampunk and a touch of Sherlock Holmes. Dolley is a master at capturing and blending all these elements." --SF Revu"Another terrific addition to this hilarious series about Reggie and the indefatigable Reeves plus the delightful Emmie, who is as zany as Reggie, facing down a time loop, a squadron of aunts, and don't forget The Mustache."--Sherwood Smith, author of CROWN DUEL"Chris Dolley's steampunk Reeves and Worcester mystery series is always a delight, but Deja Vu Halloo sets new heights of insane brilliance. Give yourself time to savor the delightful absurdity!"--Patricia Rice, author of the School of Magic series
