How about getting him a collection of poetry books written by some of the best slam poets out there? Some good options include "The BreakBeat Poets Vol. 2: Black Girl Magic" edited by Mahogany L. Browne, Idrissa Simmonds, and Jamila Woods, "No Matter the Wreckage" by Sarah Kay, and "The Crown Ain't Worth Much" by Hanif Willis-Abdurraqib.
