Woman of a Certain Rage by Georgie Hall

Eliza Finch is angry, very angry and very very hot.  Eliza, wife, mother of 3, jobbing actor, cake baker, wine drinker.  Now 50, also cursed to be a sweaty, sleepless over-thinker. 

The truth is she does not feel any older.  Although she knows thats's seen as risible, women her age grow braver, bolder and almost completely invisible.
