This is Book Three of the Hope/Despair Series and currently has no title.  This is the book where Vioda is finally introduced.  It's unclear (at this point) whether this will be the last book of the first series or whether there will be one more.  So, potentially, the climax of series one will culminate at the conclusion of this book.  At the very least, other characters included will be Eleni, Eluin, Monica, Karthik, Diraxi, Terry, Cole and Sanso.
