Stella, I believe the Grindstone ends very soon, so suggest you hurry.
I don’t know about the Bath children’s award, but agree they have a steep entry fee. It’s also £25 for the novel award.
The novel award is highly regarded, and all the winners have ended up with a deal. (For a male writer, though, it’s worth knowing the award is female-administered, has always had a female judge, and always had a female winner. These are simple statistics – I’m not reading anything into it other than women have outperformed men.)
My greatest expense this year has been my novel: a professional critique, then FOW18. If I don’t have success with it, my greatest expense will be alcohol.
