Sevana Warran is a prodigy; she is an Artifactor prodigy which means she can make a magical artefact for helping with practically any life problem given enough motivation and time. Speaking about motivations, a serious challenge is a good one, like the one where she takes on removing a curse from the kingdom's Prince. This curse keeps him from growing up resulting in 20-year-old guy being stuck in 8-year-old body. A group of very powerful people in the kingdom wants to keep things this way: they can control the kingdom by keeping the cursed prince isolated.
Sevana is so fed up with yearly paperwork of renewing her professional license she decided the lisence with no expiration date for the curse removal would be more than adequate price for her service. There is a tiny matter of getting the Prince away from his virtual imprisonment, but such minor details would never be able to stop an Artifictor of Sevana's rank.
This book is not grimdark fantasy; if you are looking for this, look elsewhere. This is as far from grimdark as possible while still remaining on the same planet. I would not call it children book, but it does have some resemblance. It is more fitting to call it a young adult book for very young adults, except that these days this became synonymous to romance and it is practically absent here.
If I am asked to describe the novel, the best description would be "a case study of interesting characters in interesting situations". It is not about how to get out of such situations; usually it is just the matter of Sevana building yet another magical thingy.
Speaking of Sevana, she is an interesting character, and so is the Prince. It is also very interesting to see his development from a child to an adult during the course of the book.
The novel is an easy read which while has its own problems still worth 4 stars. Among the problems is the length which is slightly bigger than it should be. From what I understand, this book despite being the first in a series works fine as a standalone as it finishes the story completely.
