Thanks to HarperCollins and Edelweiss for sending me an eARC of this book in exchange for an honest review. 
 This is a spoiler-free review for One Dark Throne but BEWARE OF SPOILERS FOR THREE DARK CROWNS.

 THIS IS NOT THE LAST BOOK. I repeat. This is not the last book. Kendare Blake you sneaky little fox, you made me read faster because of anticipation (and the thought of this being the final book), only to find out that there will be another book! WHYYYYYYYY. I thought this was a duology?!?! Not that IaEUR(tm)m complaining though, I still want more Fennbirn drama to be honest, but now I need to wait another year for it. AGAIN.

 After the total chaos of the Quickening, things are heavier and darker now that the Ascension Year has begun. Arsinoe, Mirabella, and Katharine must find waysaEUR< to kill off one another until only one remains to rule the island. The only problem is, not all are willing to kill for the crown. 
 Like I said, this a spoiler-free review. Therefore, IaEUR(tm)ll make my thoughts and/or opinions quick to avoid spoiling you guys. 
 The time has come for the three queens to kill for the crown, loyalties are tested, and new alliances are formed. In other words, shit is about to get down. *sips tea*
