The Witch of Blackbird Pond

The Witch of Blackbird Pond is a 1958 historical novel by Elisabeth George Speare, set in the historic town of Wethersfield, Connecticut.

Kit Tyler is thrown into the subdued, rough life of a Puritan. After her upbringing on a rich plantation on Barbados, obedience and religious piety are hard pills for her to swallow. She learns to bear her new life by befriending an outcast old widow, a neglected child, and the playful sailor whose ship ushered her to her new home. Kit slowly tries to fit in until accusations of witchcraft threaten to undo everything, and may cost her her life.

Tropes used in The Witch of Blackbird Pond include:

Aborted Declaration of Love - When John comes to ask for permission to marry Mercy, Judith mistakenly thinks he's come to ask for her hand. When he realizes what has happened, he keeps quiet for sake of embarrassing everyone involved.
Abusive Parents - Goodwife Cruff is this to Prudence, while Goodman Cruff is too much of a Henpecked Husband to stand up for their daughter until towards the end of the book.
As the Good Book Says... - As the book is set in Puritan New England, many characters quote and read from the Bible at length.
Broken Bird - Nat fears that this will become Kit's fate in the harsh social environment of Wethersfield. He even compares her to a bird he once wanted to buy on a tropical island, but his father explained to him that it would die if he brought it to New England.
Cannot Spit It Out - The unspoken love between Mercy and John is in serious jeopardy due to their inability to spit it out. When John's confession of love is mistaken to be aimed at Judith, Kit is screaming inside for him to spit it out, but he still can't manage it.
City Mouse - Kit is a formerly rich city mouse from Barbados who comes to live with her aunt and uncle in the small Puritan colony. She has incredible difficulty adjusting to a homely life where a silk dress is considered frippery by her uncle when she was raised with slaves and finery as a plantation master's granddaughter.
Cloudcuckoolander - Hannah is an isolated old woman, nearly blind with age, who practices an outcast religion, has been accused as a witch and heretic more than once, and often forgets her husband is no longer among the living.
Big "Shut Up!" - When Goody Cruff tries to break her husband back down after he stands up to her, he delivers one to her and orders her home, speechless.
Everything's Cuter With Kittens Hannah's cure for sad children is blueberry cake and a kitten. It never fails.
First Boy Wins - The first character we're introduced to other than Kit is Nat. He finally comes clean about his feelings in the final chapter.
Fish Out of Water - Kit, the aforementioned City Mouse, transplanted from Barbados to Puritan New England.
Henpecked Husband - Goodman Adam Cruff is very much under the thumb of his wife, so far as he doesn't dare speak against her abuse of their daughter.
The Heretic - Hannah is described as a heretic and witch because she refuses to attend Sunday Meetings. Several of Kit's free-willed acts are called heretical.
Identical Grandson - Judith and Kit look exactly like their mothers Rachel and Margaret respectively. Kit's resemblance to her mother is so startling to her aunt that she nearly falls over on seeing her the first time.
Ill Girl - Mercy's poor health and lame leg are the result of a fever she caught as a small child.
I Want My Beloved to Be Happy - Mercy refuses to speak a word of her love of John Holbrook to anyone. Even if it means watching him marry someone else.
Lap Pillow - Upon his return from the militia, John Holbrook (who was believed dead) comes straight to the Wood household. Everyone is shocked to see him alive, but all he can bring himself to do is wordlessly stumble across the room to drop to his knees and put his head in Mercy's lap.
Love Dodecahedron Judith has a crush on William who falls in love at first sight with Kit. Judith abandons her plans for William when she meets John but her sister Mercy is desperately and secretly in love with him. John loves Mercy as well, but becomes engaged to Judith in a horrible misunderstanding. William courts Kit for a while, but she realizes she could never be married to him and breaks it off. John goes missing and is presumed dead and Judith is comforted by William. John returns and confesses his love for Mercy. William and Judith have fallen in love as well and they plan to hold a double wedding. Kit runs off with a sailor. Whew!
Love Epiphany - In the final chapters, Kit realizes that her hopes and dreams aren't truly about going back to Barbados, they are about sailing by Nat's side again. She's shocked to realize she loves him, and spends the rest of the winter anxiously awaiting his return.
