Dear Dr. Pihlaja,
Or ended worse:
We are sorry to inform you that, despite being sound and solid, your proposal does not fall within the aim and scope of this publication. We appreciate your interest in this project, and look forward to working with you in the future. If you have any questions regarding this book, please do not hesitate to contact us.
You win some, you lose some. The book, Literary Education and Digital Learning: Methods and Technologies for Humanities Studies, should be good, though. Even if I'm not in it.
