You are my Sunshine by E. Broom

Dr Justice Jackson is grumpy, having turned his back on magic and his deranged family years ago. He enjoys his work but is having a struggle, as most of his patients prefer witch potions over scientifically proven medicine.
But now his secret is out. He is descended from a dark line of witches, a secret he’d promised himself he would never reveal. But Alfred Stone, the always happy, bouncing shifter, had been in danger, and Justice used his magic to save him.
Now Justice had a choice: hide from the Stone family and Alfred or embrace his witch side.
Justice is all for hiding away, but when a new man comes to the town and takes an interest in Alfred, Justice realises that he might have left things too late.
With friends rallying around, dark witches on the hunt, and the townsfolk watching on, can Justice and Alfred have a happily ever after? And will they score a perfect ten?
