Rewording help needed

[Juliana]

In the original version in the first post you repeat 'their pasts'. So if you're redoing the second para, maybe change that a little so it doesn't feel repetitive?

Washed up on a beach with no memories, desperate to recover their pasts, Orc and Cass have no idea of the danger they pose to the world if they fall into the wrong hands.

As the strain of what lies buried in their pasts

Well spotted. I was wondering how noticeable that was, and couldn't think how to reword it, but in the end I just left "in their pasts" out of the second para.

As the strain of what lies buried begins to tear them apart ...

I assume it's obvious enough that it means in their pasts?

Perfect.
