Ruth, first of all, THANK YOU so much for responding to the call for supporters. May God pour His blessing back on you one hundredfold for what you have given.
Anyway, as Jan said, you will need to really fly to get your entry in this year's Page Turner, but don't let that hold you back.
This year's contest is aimed totally at fiction, so as Jan said, if your entry is a fictional mystery story, then you are right to enter. If it's a true story, though, then save that for next year's contest (which will be for non-fiction and will run from the 1st January through to 31st October, 2010).
If you've got a manuscript for a novel in the works now, hope to see you in the Page Turner list.
