Despondency

Currently, I'm working a book which I titled Despondency. The main idea was to portray the pains of a cheating spouse but the book will end up with numerous plot twists and thriller scenes. The book is set in a fictional town in Lagos with surrounding areas like Victoria Island, Ikeja and Surulere.
Susan used to think she had a wonderful home with a loving husband and the most adorable daughter, until reality hit her in the face.
At first, it started from her partner returning home late, then the calls started coming.
She wanted to believe what she knew wasn't true even though the signs were evident.  Even though she knew the truth.
Soon the quarrels start and little Charlotte is caught up in the middle, Amanze moves out of the house and this causes a greater heartbreak.
Charlotte, young as she was becomes suicidal gradually, now Susan is faced with a double task.
How long before she loses everything she loves and worked so hard to keep? How can she hold on to the sharp pieces of her life even though it is piercing her and making her bleed?
