Just in time for holiday season, the first omnibus edition of the Armada Wars novels is now available to preorder for Kindle. The release date of July 1st is very likely to be brought forward into June (edit: release date was moved to 1st June 2016, and the omnibus is now available).
This omnibus contains volumes 1-3:
They are all the latest texts (which this week have also graced the individual Kindle editions, and the new paperbacks), and the SFTD version is the third edition.
It might seem weird having an omnibus of the first three books of a five book story, but it's simpler to have this now and later release a second omnibus of the last two books (and probably the novellas too). Kindle pricing and royalty structures sort of dictate it.
The book is almost 300,000 words long, so it's a whopper. The price of $9.99 USD (£6.99) represents a saving of about 15-18%, depending on what Kindle region you use.
In all likelihood this is of more use to your friends than it is to you, so do please share!
If however you have only bought the first book, it may still save you money if you buy this edition instead of getting the sequels separately... even if you dropped lucky with a freebie day or a countdown deal.
