I had no idea this novel was a reimagining of the "Island of Doctor Moreau" by HG Wells. Set on the back of the Caste War of Yucatan, we are warned from the first pages that due to its isolated position the peninsula has often been confused with an island. Carlota has a calm life with her father in a remote mansion where the Doctor leads his research financed by wealthy farm owner Lizalde. All's well until the son of Lizalde finds out about them.
