In a small publishing company, there are three authors: Maya, Luis, and Sofia. Each author has an editor assigned to them: Maya's editor is Dr. Clark and Luis's editor is Ms. Turner. Sofia's editor is also Dr. Clark. Luis and Sofia are collaborating on co-writing the same book, 'How to Kill Time', while Maya is writing a book independently, titled 'The Revenge of the Clowns'. Explain the relationships between the authors and their respective editors. Also explain the involvement Maya has in the writing of the book 'How to Kill Time'. Finally, explain what project or projects Dr. Clark is involved in. Provide a short response.
Maya's editor is Dr. Clark, establishing a writer-editor relationship. Luis's editor is Ms. Turner, indicating a writer-editor relationship as well. Sofia's editor is also Dr. Clark, creating another writer-editor relationship, and she shares the same editor as Maya.

Luis and Sofia are co-writing the book 'How to Kill Time', which does not include Maya as an author. Therefore, Maya has no direct involvement in the writing of 'How to Kill Time', even though she shares the same editor as Maya.

Dr. Clark is involved in two projects: editing Maya's book, 'The Revenge of the Clowns' and co-editing Luis and Sofia's collaborative work, 'How to Kill Time'. For the work titled 'How to Kill Time', Dr. Clark is working along with Ms. Turner to co-edit the book.
