"Doyle has hit upon something rare. An original approach to climate fiction."

BOOKLIFE REVIEWS

"...readers who enter Hibernaculum with the characters, who come to realize that its promises may be empty and hold consequences they never saw coming, will find the story gripping, revealing, and frightening. The contrast between notes and experiences of those who navigate this world are exceptionally well done, and will lend to book club discussions and sci-fi reader delight. Libraries and readers seeking a futuristic exploration which examines sleepers of the world and the social and political truths and realities that underlie their motivations will find Hibernaculum replete with a growing horror of realization that awakens, at the end, into a nightmare of manipulation and truth. It will leave readers thinking long after the story's final startling revelations.

DIANE DONOVAN, MIDWEST BOOK REVIEWS

In this compelling science fiction novel of speculation, author Anthony Doyle presents a distant future in which human hibernation has been perfected. Some enter the Hibernaculum as a means of prolonging their lives. For others, it's a means of survival in a world they can ill-afford to live in 365 days a year. HIBERNACULUM peers into the lives of some who have hibernated, some who haven't, and some who are on the cusp. Beneath it all lies a sinister truth that will leave you breathless and contemplating our own world long after you've finished the final, revealing chapter.
