Destiny is a mostly fitting conclusion to this excellent trilogy; there is an evolution in the story from book to book which works well. In the first book we are introduced to the core characters and Haydon invests valuable time in their characters and relationships - and in our feelings for them. In the second she began to weave in the much bigger picture of their new world and all the threads and prophecies come together well in the third.
This third volume is a rewarding but slightly frustrating read. I found myself rooting for the characters when they were in danger, found myself seething with anger at injustices, frustrated when they were thwarted and thrilled when they succeeded. There are some extraordinary battle scenes, a well-developed world, intriguing (and sometimes slightly dark) heroes and much besides. Haydon has been extremely ambitious, and successful, in establishing her world (possibly with a view to further novels in the same setting).
In her attempts to create such a deep, broad and rewarding tale I do think Haydon has slightly over-engineered this final instalment, especially towards the end of the novel. She has, in my opinion, fallen into the trap for fantasy authors of creating characters that are too powerful. There seems to be nothing that Rhapsody in unable to do, ditto Achmed, Grunthor, Ashe and numbers of others. It became difficult to conceive of an enemy who could challenge such an array of heroes and in the process much of the tension vanishes.
And so it proves. The battle with the demon becomes a footnote, rather than a thriling denouement to the trilogy, and instead the novel ends with a less than satisfying contrived finale with characters whose involvement had previously been minimal. I had so much enjoyed so much of the trilogy that I felt a bit cheated.
