Jovian Heat

There was a storm brewing in Gravstead, but all Cass wanted was to go home, soak in a metallic bath and ride out the hormonal storm that affected every Jovian female, heavy and guppy alike. But when her old partner brings her a time-sensitive case involving a half-breed infant, she can't say no. Someone has to find the father and make him pay for the genetic resequencing to save the baby's life.

The only problem - the father died months before the child was conceived.
