Vengeance at Midway and Guadalcanal is consistently holding in the top 2-3% of kindle books. Project Seven Alpha has been boosted by the MWSA Historical Fiction for 2012 nomination and is holding between 5 and 10%, the nominations can also be viewed on goodreads. Even though it is a recent release in kindle, p7a has done well thanks to my readers! In fact it is gaining momentum faster than Vengeance did.
I am currently editing the third in the trilogy: End Game in the Pacific. Look for excerpts soon.
