What's your favorite book that you wouldnt say is a masterpiece?

Mine is the wings of fire series, it is a "kids" novel (think like warrior cats age range)

But Tui T sutherland is so good at writing characters and introducing and describing worlds and characters that i reread it every so often. Like, she managed to write a book from the pov of a mind reader and it works.

Every book is from a different character's pov and each character feels wholly unique.

The main issue with the series is that the plot is kinda average at best, the characters really carry the story.
