Warm Bodies, Cold Hearts — Rachel E. Rice

When Sydney and Danny meet sparks fly and ignite a fire that will burn through love, sex, drugs, and hate. There has never been such a love hate relationship such as Danny's and Sydney's, where they would try to destroy each other if they can't have each other. 

Sexual bonds fall, friendship falls, but Danny and Sydney find a way back to each other through a journey of betrayal and infidelity.
