I loved this series. After Dragonclaw (without a doubt the best one in terms of achieving breadth and depth) the books present themselves in a sort of shopping list, where a challenge or two is crossed off the list in each book, until we reach the resolution at the end of book 6. They lose the depth and take on a more young adult quality in their ease of reading.
But none of that mattered to me. Sure I could easily finish a book a day if I felt so inclined, but I fell hard for the characters and the world. And I eventually got over the fear of losing beloved characters that writers such as GRRM instilled in me. It's a Happily Ever After series that doesn't punch you in the gut out of nowhere. If unexpected deaths of supporting characters provides a morbid sort of pleasure for you, you probably will find this series boring. And yes, it becomes predictable once you realise Forsyth isn't out to kill off beloved protagonists and minor characters, and that she's intent on tying up all the loose ends into something resembling sunshine and rainbows.
I couldn't give it anything less than 4 stars though, because I don't think these are bad things when the writing isn't bad, the cast of characters are endearing, and the entire world is so lovingly crafted. Since this was only my first read through, I can't say there are no plot holes but it looks as though there weren't any glaringly obvious ones, because I can't recall any now.
The only criticism I can think to give right now is I wish that Isabeau had unleashed more badassery. Don't get me wrong, changing into a dragon and burning her enemies is pretty bloody badass, but it was slightly anticlimactic. For such a powerful sorceress, it would have been nice to see her dropping more magic on people's asses. A true pacifist, our 'Beau.
Anyway. Will definitely read again. Probably starting next week.
