There isn't a book Odysseus. You're probably thinking of Odyssey.
Some Calypso quotes from Homer's "Odyssey" include:
To have some company and because she loves him.
him leaving calypso's island the sirens etc
Zeus sent Hermes to order Calypso to free Odysseus and send him on his way home. Calypso greeted Hermes and honored him with ambrosia and red nectar. He told her of Zeus' demands as they ate. She was upset that Zeus would ask her give up her lover but she did not refuse. If Odysseus wanted to stay with Calypso then Zeus would permit it, but if Odysseus wanted to leave, Calypso could not use her charms to stop him. She thought that Odysseus might change his mind if he understood her love and power. She offered Odysseus immortality and endless youth but he was determined to return to his home or die trying. Calypso accepted her fate and agreed to let Odysseus leave unhindered. She refused to supply Odysseus with a raft or ship but she gave him some tools and the skillful Odysseus built a raft for himself. When it came time to leave, Calypso in her loving nature, gave Odysseus provisions and sent him on his way with a fair wind to speed him home. Calypso and Odysseus had two daughters, Nausithoos and Nausinoos.
In Greek mythology, Calypso's children were Nausithous and Nausinous. They were believed to be fathered by either Odysseus or Poseidon.
Besides a Goddess, Calypso is considered to be a temptation to Odysseus, which in some cases are true. He was willing to be with her for years, although his heart still longed to go back to Ithaca and be with his wife. Calypso is not exactly like the other obstacles/problems Odysseus faces, it is just that she basically prolonged his trip to return home to Ithaca.
In Book 9, Odysseus reveals his arrogance and lack of self-restraint when he tells Polyphemus his true identity, leading to dangerous consequences for his men. Odysseus's lies and deceit, such as pretending to be a beggar upon his return to Ithaca, show a lack of integrity and honor as a hero. His prolonged absence from home and dalliances with other women, like Calypso and Circe, demonstrate a lack of loyalty to his wife, Penelope.
He doesn't escape, he's let go. After Zeus says it's time to send Odysseus home, he describes what will happen on this last leg of the journey. Then, he send Hermes to tell Calypso it's time to send Odysseus away. She gives Odysseus some tools, they go into the forest and he builds himself a ship. She gives him some cloth, he makes sails. She supplies him and send him on his way.
In Greek mythology, Odysseus did not have children with Calypso. Although he spent several years on her island, Ogygia, Calypso kept Odysseus as her lover and wanted him to stay with her forever. Odysseus eventually left the island and returned to his wife Penelope in Ithaca.
In Homer's "The Odyssey," three main characters fall in love with Odysseus: Calypso, Circe, and Nausicaa. Calypso is a nymph who keeps Odysseus on her island against his will for seven years. Circe is a sorceress who turns some of Odysseus's men into swine and later becomes his ally. Nausicaa is a princess who helps Odysseus when he washes ashore on the island of Scheria.
He cheated on his wife with Calypso and Circe, he let his men die, and insulted the gods. However, most of these were not done on purpose. He was literally trapped on an island with Calypso, who was a beautiful nymph, for 8 years. Just him and Calypso. His men were stupid in the fact that they ate Helios' cattle when told not to. This insulted Helios, who requested Zeus to punish Odysseus. Also, to get past Scylla, he HAD to sacrifice six of his men in order for Scylla not to destroy the ship. Finally, he blinded Polyphemus, who was Poseidon's son (no known to Odysseus), to escape his island. Odysseus was cursed accordingly each time he insulted the gods though, so it evened out.
Circe is the sorceress. Some people would try to tell you that Calypso is also a sorceress, but she is just an attractive daughter of Kronos, Lord of Time.
