    As I’m writing this it’s actually the first week of September, so I haven’t yet finished Crossbones. But since I’m going on a holiday, I thought it’d be nice if I prepared this post for you. Anyway, by the time I return from my holiday, I’ll have finished the book & I’ll let you know my thoughts!

    When a pirate king dies, the Blood Bell tolls, marking the start of the Trials: a competition for the Bone Crown, the coveted island thrown. Csilla Abado yearns to prove her strength to the seasoned pirates and to her elder sister. She’s willing to risk everything to become the first pirate queen.

    For Kane Blackwater, the Trials represent a new beginning, yet rumors of a secret heir are swirling, threatening his hopes of becoming the pirate king. It will give him the chance to get away from the dirty gold and shady trades he’s made to keep his father’s ship, the Iron Jewel, alive.

    Lorelei Penny is bent on avenging her mother’s death. So she stows away on the Iron Jewel to get closer to her killer. Instead, she finds herself caught up in the deadly battle of the Trials.

    All three are on a mission. However, the sea has other plans—dark tides are rising, and if they’re not careful, they’ll surely drown.

It almost consumes Artemisia, but only a vespertine, a priestess trained to wield a high relic, has any chance of beating the possessed army.

        Rose Abernethy and Beo Mataya are two strangers drawn together by one thing alone: Red Sunrise, a book no one else seems to have read. A book only asked about by either collectors or the NPV. A book Rose and Beo feel was written just for them.
