Although Shirley's book is set in ancient Egypt you can write about any period of history.
Shirley has a few tips which should help - "Historical fiction should have as factually accurate a depiction as possible of the chosen period if the fiction is to be believed. Readers are very quick to pick up anachronisms (ie no cigarettes in 1820. Sights, scents, sounds all need to work with the period).
But people lived and loved and hated and had all the emotions we have today and human nature is still the same - it's just the framework in which those people are set that's different.
Check the facts and then enjoy writing the fiction!"
If you do fancy setting it in Egypt, this might help.
Erewash Writers run regular competitions. Although not free, this one for new writers (which they define as someone whose not yet had a sale or win) might be of interest. Each entrant will get a critique and the chance of winning £40 which isn't bad for £3.
As always, read the rules and regulations carefully before enterring, rather than relying on my quick summing up. You know how scatty I can be.
Oh history! That means another excuse to sneak in one of my holiday pictures. This one is of part of Tantallon Castle. It was built around 1350 and yes it's in Scotland and yes, I did have to climb a lot of stone spiral steps to take it.
