A Suitable Girl is an upcoming novel by Vikram Seth, which is a sequel to his 1993 book "A Suitable Boy". Seth has stated that the book will be set in the present, rather than in 1952 where "A Suitable Boy" finished, and will therefore be what Seth calls a "jump sequel".
The first book finished in the present and the second one will be in 1993, after A Suitable Boy.
A Suitable Boy was the first book and it finished in 1952, not the present. The system probably did not comprehend the context.
