I just self-published a young adult fantasy horror this month. The back cover description is as follows:

"As word of a mysterious plague reaches the shores of Ireland, Banion and his friends prepare to step into their roles as knights of the southern kingdom. As the day of the trials comes upon them, they are thrust head first into madness as they face the risen dead.

Ireland faces extinction unless the young knights can spread the word of the plague throughout the country as they race north to reach the king and join the fight to reclaim Ireland's shores."

I have written a short story prequel that is available for free at http://www.thstrickland.com I'd love for anyone interested to check it out.

The novel is for sale at Amazon, Barnes and Noble.com, and through the Createspace online store.

Thank you! I hope you enjoy my writing. This is my first novel and I am eager and welcome any feedback.
