"The Reviver" — this is two amazing books in one.
The first — is a fictional biography of Dr. Spencer Black: from a childhood spent exhuming corpses, to studying medicine, traveling with carnivals, and finally, his mysterious disappearance at the end.
The second book — is the main work of his life — "Codex of Extinct Animals". It is "Gray's Anatomy" for mythical creatures — dragons, centaurs, pegasi, cerberuses, each presented in carefully detailed anatomical illustrations. Just one look at these drawings makes it clear: this is the creation of a madman. And "The Reviver" — is his story.
