Biggest literary influencers:

Greg Bear, Colleen McCullough, Connie Willis, David Weber, S. M. Stirling, Harry Turtledove, Margaret Atwood, Theodor Mommsen, Ammianus Marcellinus, Bruce Sterling.

Last book read:

The Turtledove Historical Collection, a 4 volume set by Harry Turtledove. The narrative covers the adventures of Rhodian merchant traders in the decades following the death of Alexander the Great.

The book that changed your life:

Caesar’s Women by Colleen McCullough taught me the art of describing historical details. Alternate history (like historical fiction) requires a threshold of details to make the narrative authentic. The trick is making events & characters truly vivid.

Your favorite literary character:

Lisbeth Salandar from the Millennium Series by Stieg Larsson. Salandar is the quintessential underdog. I love the way she champions women’s rights and overcomes steep odds while remaining true to herself.

Currently working on:

Hot Wheels: Cool Assassins 2 (due out in late 2019)

Words to live by:

Do the best you can. And don’t listen to naysayers.

Advice to new and aspiring authors:

Read, read, read… especially in the genres you write in.
