Originally book 7 of the Shattered Saga used to be called "Shattered Heart", but then I decided to separate n° 7 and 8 as sequel "Demon's Fate". Nonetheless it's still about shattered hearts and souls and lifes that get broken.
Too sad and full of regret to do anything. Ever feel like that? Take my heart, it's broken and in a sense betrays you? Do you sometimes feel haunted by regret and despair? We all get sad from time to time, problem is when it becomes dominate.
