Having just finished Book 7 in the series by Melissa Good, I moved on to Storm Surge: Part 1: Book 8 in the Dar & Kerry Series (Dar and Kerry Series 10) where I kept thinking I must have missed something …
It's right there in the link: even though it's named Book 8 it's actually Book 10.
A large part of the book deals with Dar and Kerry's part in assisting after the events of September 11, 2001. Frenetic! But also interesting.
