The Witch’s Empathy by Iris Kincaid

When Erin Sweeney needed a new kidney, not a single member of her family agreed to be tested for an organ match. And thus began her life of dialysis and disillusionment.
It’s a funny thing about losing your last functioning kidney. Not funny ha-ha, of course. But peculiar how it can lead to the loss of so many other things – friends, family, job prospects, and any hope of a love life. Erin Sweeney knew exactly what everyone must be thinking about her. Her weakened condition and dependence on dialysis undoubtedly filled the people around her with pity and revulsion.
In life, Lilith Hazelwood was the most powerful witch in Oyster Cove. In death, she is determined to find and punish her murderer. Once enraged by the fact that her body parts had been used for organ transplant, she now sees the beneficiaries as the best means of avenging her own death. If they would only stop being sidetracked by silly diversions like solving human murders and finding love.
Erin always knew that a kidney transplant would be her ticket to health and normalcy. But she had no idea it would unlock a gateway to tap into her elusive sixth sense – the ability to read minds. Which is not as much fun as it sounds. Do you really want to know what the cashier thinks of what you’re wearing? And more importantly, do you really want to know that you’ve been spending time in the company of a murderer?
