These four stories, alternating between the two authors, are all excellent. They are interesting, with wonderfully written characters - and each shines a different light upon the problem of magic use causing the brambles. Each story has its own ending, but with all four of them on the same topic, they easily bleed right into the next one. You really won't want to stop reading.
I do hope that there will be more stories to come from Khaim - there are a couple that ended in which I would love to have some follow-up on the characters and what ended up happening AFTER. Will there ever be an answer to the all-or-nothing problem of the magic and the deadly thorns? Or will the people of that land simply continue to do as they have done, until one day, the world is nothing but the deathly plant?
Honestly, it was initially the cover that drew me. However, in this case, come for the cover - stay for the stories.
