DIVIDED EDEN, Charlotte Kilmartin’s debut novel, is set in a divided Edinburgh where a genetic mutation can set you apart, but not set you free. On E.J.’s thrilling journey from city to the wilds of northern Scotland in search of freedom, appropriate hair product and an end to the sickness being brought against her kind, E.J.’s humor never fails her. Nor her love of Tunnock’s teacakes. (Seriously, you’ve got to try one.)
