how long did it take to write MASK OF DRAGONS?

How long did it take me to write the rough draft of MASK OF DRAGONS? The chart below shows.

Actually, I wrote the first 19,000 words of the book while finishing up FROSTBORN: THE HIGH LORDS. In 2015 I got into the habit of working on two books at once, which has proven useful.

So I started MASK OF DRAGONS in January while mostly working on FROSTBORN: THE HIGH LORDS. Then in February I switched focus entirely to MASK OF DRAGONS, which let me finish it in a quick burst.
