not a book or anything but I think vortigaunts from Half-Life function somewhat like this. they're telepathic and each has a sort of hive mind-like connection to but it's more of a network of individuals than a true hive mind.

I think in the original Half-Life most if not all creatures from Xen were part of the nihilanth hivemind

vorts were specifically not, they were slaves of the nihilanth. their in-game name is monster_alien_slave, and thats why they all wear those glowing green contol collars and why several on Xen refuse to attack Gordon unprompted.
