Pairing: Mako Mori / Chuck Hansen
Fic Title: The Old Man and the Sea
Link: The Old Man and the Sea
Genre: Angst (just a bit)
Why This Must Be Read: There aren't many Mako/Chuck fics out there but if you think about it, it could work. They have much in common, both have lost parents because of the Kaiju, they're second generation Rangers who grew up around in the PPDC and strive to surpass or prove themselves to their parents.
This fic has them growing up together, growing apart and then reuniting. It's wonderful how the author shows them dealing with their grief and anger in totally different ways.
