Has anyone read this series by Markus Heitz? What am I in for?

Looking for advice.
Want to give my mother a fantasy book readable for her.
She's not experienced. Knows lotr on a rudimentary level and liked Harry Potter.
I noticed pick related on her coffee table, read some and thought the writing was retarded and she didn't enjoy it at all.
Anyone know of something that would suit her?

There is so much it's hard to find something suitable. My knowledge of fantasy is starter level: I've read lotr, silmarillion, first two trilogies Thomas Covenant (to dark and psychological for her), asoiaf (not fantasy enough).

Would appreciate some advice!
