Shattered Pillars is a very transitional book that mostly continues the plot points introduced in Range of Ghosts, with additional complications as the bad guys and good guys play Spy vs. Spy. Temur continues his quest to rescue his lover Edene, unaware that she has already escaped. Edene in turn is unaware at first that she was actually allowed to escape. (Nor, when she finds out, is she able to do very much about it.) He also continues his plan become Khagan.
