The fourth book of Allan's planned five books in his Immortal Treachery series introduces quite a few new storylines and characters while also filling out the storylines of the major characters from the previous books. All of them have new and exciting adventures and most also develop new abilities and talents, fleshing out their characters beyond what we already know about them. There are many skirmishes but the big battles are being held off until the finale, as the storylines develop to fruition and convergence. As a getting ready for the ultimate showdown kind of book, it's got a lot of new persons, places and action, as well as some pretty big shocks along the way. Faithful readers of the series will be happy with all the new stuff here while also getting ready for it all to come together. That's going to be a major task because of all the storylines and characters who are now involved. Its made me want to see the conclusion even more and as such it has succeeded as a precursor to the finale. My rating is 9.7 out of 10.
