The books are easily simple enough for children as young as seven, but not sophisticated nor complex enough to be captivating for older readers (10/11 +). They are enjoyable, and the storylines could be made into something truly exciting and intriguing, but the format, which is limiting, and the emotional sparseness of the narrative, hamper the books. There is also far too little character development. And the series lacks subtlety when it is needed most, stating the obvious, and then becoming vague when clarity would be advisable. Especially for Jasmine, who is a central character, but receives very little attention, certainly not as much as she deserved and which would have really fleshed out the story, deepening the impact of her relationship with her father, their friends and allies, and esp. Lief.
Dain was a surprise, first one in the whole series for me. But a very weak conclusion, even with the two other series. 2.5 stars
