Praise for

The Doomsday Vault

“Harper creates a fascinating world of devices, conspiracies, and personalities. . . . Alice and Gavin fight to survive and to find love in this steampunk coming-of-age story. Harper’s world building is well developed and offers an interesting combination of science and steam.”

—SFRevu

“You’ll have great fun exploring the Third Ward, and the author created such a rich and lavish world for his characters. . . . Twists and turns abound, and the author managed to lob some shockers at me that I’ll admit I didn’t see coming. . . . If you love your Victorian adventures filled with zombies, amazing automatons, steampunk flare, and an impeccable eye for detail, you’ll love the fascinating (and fantastical) Doomsday Vault.”

—My Bookish Ways

“The Doomsday Vault is a good way to start off a new series in a highly specialized genre. Its combination of science and fantasy and good versus evil work well . . . a clever and worthwhile take on the steampunk universe.”

—That’s What I’m Talking About

“A fun and thrilling fast-paced adventure full of engaging characters and plenty of surprises. . . . I particularly enjoyed all the interesting and unexpected twists that kept popping up just when I thought I had the story figured out.”

—SFF Chat

“The great thing about having all these awesome characters is that [they’re] all snuggled up against a really great plot, several intermingling subplots, and pretty dang great steampunk world building. And excellent writing. . . . [The Doomsday Vault is] fun, funny, and a damn fine romp of a read. So much goodness packed into this book! Highly recommended.”

—Lurv a la Mode

“A goofy excursion in a style reminiscent of Foglios’s Girl Genius graphic series. . . . A highly entertaining romp.”

—Locus

“Paying homage to the likes of Skybreaker, 2D Goggles, and Girl Genius, The Doomsday Vault is awesome. One of my favorite steampunk-zombie novels. Abso-freaking-lutely recommended.”
