You know how I say I told my friend what had happened before she came to class.
Above is a time line in red. Time goes to the right. Its arrow is the present. "came" is in the past, a little back in time. I told my friend what had happned. "what had happned" is whatever happned up to the point my friend "came".
NOW. I want to say what's similar but in the present tense.
In this book, Jeremy tells his friend what has happned before she came to class
Is this grammatical?
