As someone who may have a similar problem with books and time …, I find the New Books Network podcasts super helpful, even just reading the episode descriptions. The have a channel focused on ancient history https://newbooksnetwork.com/category/history-1/ancient-history
@camilla_hoel My approach for questions like this is to look up the topic on Wikipedia, go to the Further Reading section and see if there's anything by a reputable non-academic publisher. In this case there's nothing that exactly fits the bill. There's one from OUP: Kenoyer, Jonathan Mark; Heuston, Kimberly (2005). The Ancient South Asian World. Oxford/New York: Oxford University Press. ISBN 978-0-19-517422-9.
And another from a publisher I've never heard of: McIntosh, Jane (2001). A Peaceful Realm: The Rise And Fall of the Indus Civilization. Boulder: Westview Press. ISBN 978-0-8133-3532-2.
My other approach is to see if fivebooks.com has any recommendations. They suggest a travelogue/history: Empires of the Indus: The Story of A River
