In too Deep?

We haven't yet got the cover of book 5 but here we do have book 6, In too Deep!!!
In too Deep, written by Previous writer Jude Watson, is out November 3rd and looks pretty cool!!!
Here is the writing on the back of the book.
'A hint from their parents' past puts Amy and Dan on the trail of secrets their grandmother Grace would NEVER have wanted them to know. Awful memories begin to crowd in on Amy, just as her enemies circle closer. How far would she go to protect Dan? How much of a Cahill is she prepared to be? Perhaps Grace was right-some secrets are better left buried...'
I can't wait for it to come out!!!
