Mad Love by Suzanne Selfors
When you're the daughter of the bestselling Queen of Romance, life should be pretty good. But 16-year-old Alice Amorous has been living a lie ever since her mother was secretly hospitalised for mental illness. After putting on a brave face for months, time is running out. The next book is overdue and the Queen can't write it. Alice needs a story for her mother - and she needs one fast. That's when she meets Errol, a strange boy who claims to be Cupid, who insists that Alice write about the greatest love story in history: his tragic relationship with Psyche. As Alice begins to hear Errol's voice in her head and see things she can't explain, she must face the truth - that she's either inherited her mother's madness, or Errol is for real!
