Find That Book

Hi everybody!

So the details I remember are:

Good vs evil in both the real world and parallel world

The setting of the book is an old school but there is also a parallel world (of sorts) where there are dragons, kings and all that stuff so that version is like a medieval fantasy one. You can only go to that parallel world and back on certain times a year. People from the school also have like, soul twins(?) in the parallel world. For example there is a professor in the school who knows these things and mentors laura, his other version in the parallel world is a king and I remember both of them getting hurt or sick if either of them gets hurt or sick. And the protagonist needed to save the professor/king at one point because of this(one of them was poisoned I think?) I think she had to get something like the holy chalice or something like that to heal the guy but I’m not sure

The main character was a girl called Laura (%90 sure) she had telepathy, telekinesis and other abilities like that. She basically helps the professor and other good characters by having secret confrontations with the evil guys in the real world, she also goes to the parallel one to help out with stuff.

I think there are 5 or 6 books in the series and I’m %100 sure the main heroine forgets everything and loses her powers to win against the evil at the end. And then a new student arrives (and it is implied that the new guy has her abilities and he/she will take the protagonist’s place now) and it ends like that

I remember a dragon eating a character in the 4th or 5th book I think?

I also remember that the protagonist has a confrontation with a sfenks(sphynx?) in the parallel world and she escapes by answering her riddle correctly.

I also remember that the evil people try to kill the protagonist and her mom when she’s little, they put some hellhound like dogs on the road when they are in a car and her mother drives the car down a cliff to the sea to not hit them, her mother drowns but an angel or something saves the protagonist

I think she also has a brother who has no powers BUT I’m really not sure about this one

I think I read this book around 7-8 years before? I think it was a new book back then but I’m not sure.

This is about all I remember from the books. If anyone can help me out I’d really appreciate it, thanks in advance everybody!
