If you're a debut novelist, with 'experience of single parent family life' and have written a book which celebrates single parent families, you can enter this competition. (There's a bit more info here.)
The competition is run by Trapeze in association with Gingerbread and The Pool. You'd think that would give me plenty of scope for an illustration, but this was the closest I could manage.
The requirements are quite precise, but that means competition might not be as fierce as for other more general competitions. The prize is excellent – £10,000 a publishing contract and mentoring.
