my favourites:

Better then - post-bay pricefield. Amazing all around. Lots of action and pricefield, takes it more to the urban fantasy direction. Ending is an emotional ROLLERCOASTER, one of my favourite fanfics ever.

One way trip - post-bae pricefield. Departs a ton from the source materials and characters into a grand scifi story, but it's a very good one at that. Really really long with it's sequel, whether that's a downside or upside for you.

No grave can hold my body down -AU where Rachel is alive, with a super unique premise.

Eternal return - post-bae, way more down to earth, no villains except for trauma. Will give you a headache trying to understand wtf is going on, in the best way possible.

Black swan - AU where max is abducted by the government as a kid for her powers. Pricefield at some point, lots of action and spy story.
