My Phantoms by Gwendoline Riley

Bridget's mother is dying. An extrovert with few friends who has sought intimacy in the wrong places; a twice-divorced mother-of-two now living alone surrounded by her memories, Helen (known to her acquaintances as 'Hen') has always haunted her daughter. Now, as together they approach the end, Bridget looks back on their tumultuous relationship - the performances and small deceptions - and tries to reckon with the cruelties inflicted on both sides.

With so little time left, can these two warring women find a bruised accord?
