By Schism Rent Asunder (Safehold)

This book only served to force the reader to want more; leaves you off at a sort of cliff hanger, I'd say. But I have to agree with other readers on this, the move Cayleb made to make Nahrmahn part of his empire at a relatively high rank was clever. instead of fighting someone who is plotting against you, convince them to plot and scheme for your side.
