Horus Heresy: Skip to Old Earth?

Hello all. Question for you Horus Heresy lore Grand Masters:

I just completed Deathfire. And I must say it was so great getting back into Vulkan’s story again. I crave more!

Is it recommended to skip to Old Earth (book 47) to continue with Vulkan’s arc? Or should I read something in between.

I’ve already completed the Imperium Secundus arc already and Master of Mankind.

Any help would be appreciated, thank you.
