The premise of the novel 'The Azure of Solicitude' is the story of three families. The poor families of Kora and Kunjeppu reside at Kakkathuruthu, the eyot-village in the Lake Vembanadu, while rich Kuriammamothalalan resides alone at the shore-village Achankara which is beside Kakkathuruthu with a rivulet as the boundary of the two villages.

The protagonist Eappan a college going youth is the son of Kora and Tharathy. Kora has a lime making kiln, where he and his male children work. Sara the first daughter of Kora a spinster and her sisters Ely and Lilly make coir yarns using rotten husk fibres of coconut. And their neighbourhood family members earn bread by making mats using wild pineapple leaves and collecting shell fish from lake Vembanadu. Eappan loves Moly the daughter of the mats making couple and student of the same college to which Eappan goes, knowing that his father would never give consent for their marriage. It's because Moly is a lower caste black complexioned girl. Her father was once a lower caste Hindu who happened to meet Thanka a white complexioned Catholic Christian girl whom he wanted to marry. Being a destitute as well as an orphan, Thanka was available to Kunjeppu but he had to convert into Christianity. He became a Christian and married Thanka. Moly is their daughter. An acquaintance of Kunjeppu an astrologer who comes to Achankara in connection with the celebrations of Audityapooja, tells him about Moly's secret love. Being a Christian, Thanka disregards the astrologer's telling, while Kunjeppu fears it. But both of them are unable to question Moly, as they love her a lot.

Kora believes to be the successor of an ancient and noble Hindu Brahmin family which had converted into Christianity while St.Thomas the disciple of Jesus Christ visited Kerala. Sara and her sisters get coir making work at the shed of Kuriammamothalalan. Kuriamma likes Sara very much. Sara too begins to love him. Being a member of a poor family, she was dazzled seeing the wealth of the old man. She thought it was her luck to entice him. Once a Tamil vagrant future predicting dampsel had come at Kakkathuruthu and told Sara that an old man would enter into her life. Sara believes in astrology deeply and she finds the wench astrologers words come into reality. Kuriammamothalalan had married twice before and both of them had expired. He had a son in his first wife whom he had expelled from his house suspecting as the second wife's suitor. The second offspring Gita born in his second wife became dement on hearing that her father had killed her mother. Nobody knows the truth. Kuriammamothalalan's relatives and friends hated him. He was compelled to leave his native place selling all his property and bungalow and migrated Achankara where he resides now. Gita was in a mental hospital for several years and comes to Achankara after recovering the mental ailment. She loves Eappan at the very first sight and wants to marry him. Eappan's family members insist him to give assent to Gita's ambition. Eappan falls into great dilemma. Moly is pregnant and he does not know that Gita was once a dement. Kuriammamothalalan never tells about his past to anyone and he had warned Gita, not to tell anything to anyone. Kuriamma pretends that his daughter was studying in a distant college and as the studies are over, she has returned home. Eappan believes all things. Moreover, he does not want to become a poverty partner by marrying Moly. And he can not neglect the compulsion of Kuriamma, marrying his daughter. Eappan agrees and he gets married with Gita. Kuriamma had bought half of the eyot, Kakkathuruthu and had built up a bungalow there. Eappan and Gita have been given the new home as their own. Gita is unable to conceal the secret that she had been in a mental asylum for years. Eappan hears the fact from her.

On the day of the death anniversary of her beloved Kaligrandma, Moly's rice glomerations were refused by the crows. She was blamed to be a sinner. Her parents understand the fact that Moly is pregnant. But Moly does not divulge the secret fearing that Eappan's name would be tarnished. With the help of a native midwife, Kunjeppu gets rid of Moly's unchastity. Eappan has an younger brother Uthuppu, who had loved Moly in vain. She hated him. Unexpectedly one day Uthuppu drowns in lake Vembanadu. Moly's parents and all others misunderstand the dead soul and decide that he was the man who spoiled Moly.

Moly had got a crow chick whom she loves a lot. She concentrates her attention on it neglecting all other things. She does not care her parents or other kinsfolk. She believes the chick to be the rebirth of her beloved Kaligrandma, who had expired years ago. One day while Moly was asleep, Thanka kills the bird. By all means Moly collapses and dies.

Sara dwells with Kuriammamothalalan in his bungalow at Achankara, with the ambition that he would marry her one day.
