Our Wives Under The Sea by Julia Armfield

A slim novel that packs an emotional punch. Leah has finally returned months late from a deep sea dive that went very wrong. Now her wife Miri is swinging emotionally back and forth from grief that Leah was lost at sea to the joy at her return and grief again that the old Leah she fell in love with might never be coming back. Both horror story and deep dive into a marriage, Leah's transformation is two fold both mentally and physically. She is dealing with the trauma of being trapped at the bottom of the dark ocean depths in a metal bubble as well as the pressure and the toll it takes on her body. There is darkness but there is tenderness as well making this an unusual look at the tides of love.  4 stars
