“A welcome return to Mann’s alt-history steampunk world and Newbury and Hobbes’ entertaining, yet darkly occult, investigations. Based on the ending, future volumes will finally tackle the secret agents that oppose mad Queen Victoria’s tyranny.” —Booklist

For the Newbury & Hobbes Investigations:

“Darkly suspenseful.”

—Library Journal on The Immorality Engine

“A wonderful penny dreadful… It’s an unashamed galloping romp through the ins and outs of the Victorian metropolis and the lurid generic conventions of adventure fiction.”

—Paul Magrs on The Osiris Ritual

“Another fast-paced yarn that shows author George Mann is very likely on to something special here…the story lines are decadent, and Mann has a deft touch at pulling everything together in a way that leaves each installment feeling complete, but also has the reader wanting more.”

—North County Times on The Osiris Ritual

“A science fantasy novel that should appeal to lovers of both genres… one of the biggest surprises of the year and I can’t recommend the book enough.”

—Fantasy Book Critic

“Steampunk is making a comeback, and with this novel Mann is leading the charge….An engaging melodrama that rattles along at a breakneck pace.”

—The Guardian
