Carnival Mirror: Errata Corrige (90-s Arc)

Carnival Mirror (series): Two time-travels, pretty much mirroring each other: sixteen year-old Tom Riddle accidentally appears in Harry Potter's timeline, during Harry's summer after 5th year; and Harry of same timeline falls through to the 1940-s, when future Dark Lord is still in his sixth year at Hogwarts.
So we have two 'sets' of Tomarry in two different timelines.
And it seems mental, but read and you'll understand, how's that possible and what'll come out of it!

These are the series of parallel fics.

Errata Corrige (90-s Arc): Not your general type of time-travel Tomarry: this time it's "Tom visits Harry's timeline".

Author Notes:

In terms of canon, in this story the flow of events had changed from the end of Harry's fifth year (from OoP onwards), but some facts remain in canon, despite that.

"Errata Corrige" means "Correction of Errors" in Latin.

English is not my mother-tongue, though I am quite confident and also am currently working with my beta to improve the quality of the story. For now it's still unedited, will be changed to revised version soon.
