The Crossblood's Quest

When Adley Cooper stumbles upon her enemy and rival, Ivan Rivers, entering a magical opening at her school, what does she do? She follows him of course.
Was that encounter an accident or fate.
"Adley! Why did you follow me?" he complained.
Adley fell out of her daze as Ivan shook her hard "What? What was that for?" she said.
"You weren't answering me! Now, tell me Why did you follow me?"
"What do you mean, why did I follow you?"
"Yeah! Tell me!"
"You were acting all suspicious in the library. Then you pulled some books in a
random order, now that I think about it, it was a code of some sort, right? So anyway,
you pulled some books and some secret cave opened up, and you went through. Of course, I was going to follow you, anyone would!"
