When his liver also fails, his surgeon suggests removing poison wastes from Jonathan’s blood by cross-circulating it through his comatose twin, DavidIt isn’t long before the surgeon has an even better idea…This is a gripping story from debut novelist John Saxby, who under his real name is a distinguished doctor himself, and an internationally recognised clinical microbiologist.
