Can a compound key be set as a primary key to another table?

For instance i have the tables:

Books -with Primary Key:Product_ID
Client -with Primary key: Client_ID
Clients_Books -with Compound Primary Key:Product_Id and Client_ID

I want to set this compound Primary key from Clients_Books as a Primary Key to another table named: Order_Details. But I don't want to use the Product_ID and the Client_ID from the Books, Clients tables.

Does this make sense? All opinions more than welcome.
