Hi Jana,
I suggest asking the product manager to be the (chief) product owner. The individual currently assigned to the product owner role may work with the (chief) product owner in a product owner team. As others have pointed out, the entire Scrum team, product owner, team and ScrumMaster should discover and describe stories collaboratively, for instance in form of requirements workshops. There is nothing wrong with deriving stories form themes. The opposite is true: I have found it to be beneficial. Jeff's user story mapping technique follows a similar approach, for instance.
You may find the description of the product owner role in my upcoming book helpful: www.mikecohnsignatureseries.com/books/agile-product-management.
Good luck,
Roman
