I read Peter Frankopan’s history book “The Silk Roads” this summer and it was a great read. Totally recommend it.
I slogged through Raoul McLaughlin's "The Roman Empire & the Silk Routes" because it's online reviews were glowing for silk road history told with decent story telling. I still found it startlingly dry, it felt like a demonstration of how much research he did rather than a real narrative arc.
Tangentially I read half of it aloud to my little kids for bedtime, they loved the crazy names of faraway fantastical sounding places - it's about all that really redeemed it experientially. YMMV, apparently.
Prof. Frankopan definitely gives a shout-out to the Sogdians, though he doesn't spend much time on it.
