Well, obviously we didn't secure a Spring 2011 release date.
There was some delay with agreements between our publishers, so we put our writing on hold--at least for this series. Everyone continued working on other books and between the 4 of us, we've had several 2010 and 2011 releases.
In January 2011 we decided to press forward and now we are all close to finishing up each of our books. We've met over several weekends and it's been a blast to brainstorm together.
We hope to turn in our manuscripts sometime in June.
Just hit page 200 in ATHENA yesterday . . .
