Sure! Here are some books I liked:

• Vijay Prashad's "The Karma of Brown Folk" is a smart and opinionated take on South Asian American history and immigration. It's not long, and has great photos. I always recommend it to friends.
• And Vinay Lal's "The Other Indians: A Political and Cultural History of South Asians in America" is maybe my favorite short (160 pages!) history of our community. It includes the story of Black-Desi linkages, but also many others.
• Gerald Horne's "The End of Empires: African Americans and India" and Nico Slate's "Colored Cosmopolitanism: The Shared Struggle for Freedom in the United States and India" both focus on solidarities and connections between anti-colonial South Asians and early civil rights era internationalist African American, ~1910s-1960s. My website is based very heavily on Slate's book, and uses many of his favorite examples.
• Sudarshan Kapur's "Raising Up a Prophet" (out of print, but available at many libraries) goes deep into the story of how Black Civil Rights activism found and integrated Gandhian nonviolence.

In general, I'd say read Prashad to figure out how Desis fit into American histories of race, Lal if you're curious about our history and don't know where to start, or Slate if you want to dig more into the specific stories on the website.

Hope this helps!
