The reading
The bead. The reader is handed the wish that a small, unwanted, disconnected life turns into a vital one the moment something living needs you to tend it.

- caretaking/being-needed · content · spine · ~ — Mary begins as the surplus child nobody has a use for — "nobody wanted her" — and the Yorkshire verdict on such children is flat: "Them as is not wanted scarce ever thrives." The release is not being valued or chosen but being needed: she begs for the one plot no one will miss — "If it was out of the way and no one wanted it, no one could mind my having it, could they?" — and as she digs and weeds, the dead garden goes "wick" (alive) and so does she, and so does Colin, who is needed by it in turn. The payout is the disconnected life made indispensable to something that grows because of it.
The bundle. Pure caretaking/being-needed; the abundance of the blooming garden is the reward the engine pays out, not a second engine driving it.
Dual-use read. The counterfeit is being-needed as engineered dependency — making oneself indispensable by keeping the cared-for thing helpless; the book refuses it, the whole arc is care that makes its objects stronger and freer, not bound to the carer.
Verdict. The bright pole of caretaking/being-needed: a child who thrives only once a living thing depends on her.
