Carissa goes to the temple and asks a priest for a book of spells for new clerics, and gets one. There are no kidnapping attempts.
The book has diagrams for cantrips, of which Keltham's god has given him Detect Magic, Read Magic, Guidance, and Resistance, and first-circle spells, of which Keltham's god has given him Comprehend Languages, Fairness, Sanctuary, and something not in the book.
