I have loved listening to this series, in fact I have done so three times already. The first two are rather short, and mostly just entertaining fluff. But with the third book, we get something that elevates it to the pure enjoyment status: a baby dragon named Spot. (More books should have baby dragons.)
Spot is so much fun that with him also arrives character development. We see Avraniel becoming a fierce mother to Spot, transforming from a pyromaniac elf into a pyromaniac elf who is also the Mother of Dragon. But unlike her namesake, Avraniel's motherly concerns lead to heartwarming and also hilarious moments of feeding Spot with cows and hydras, teaching him to fly, brushing his teeth, and his adorable habit of cuddling with everyone.
This is pure, unaldurated, completely silly, enjoyable, pure entertainment. There is no pretentious nonsense here: we get plenty of fantasy, dragons, necromancers, zombies, and occasional musings on paperwork and the prices of shovels and pitchforks. There is lots of action with all sorts of monsters; fun, intricate plans for things like breaking out an ancient vampire from an imprenetrable fortress, and rescuing a princess from the enchanted castle of a powerful mage-crime-lord. We have enthusiastic accounts of how to make a zombie shark-whale and how to acquire kraken corpses.
This is so cheesy that it is surprising how well this story is told. The writing has that nerdy, self-deprecating quality of a high-schooler writing for fun, yet apart from the tendency to repeat phrases and words, it flows enjoyably. Estrella has a true talent for weaving a good yarn: there is lots of action, all well told, and the pacing is perfect.
If you can get past the occasional repetitions and Disney moments, this is absolute cheese of the highest order for all fantasy nerds. If you want high literature, look elsewhere.
