I was hooked by the setup in this book of a group of adopted children, partially pulled out of time by a god-like Father, and each set to learn one specific branch of knowledge and ancient power. My favorite part of this book was the slow unfurling of background machinations and scheming that all paid off in the end. The characters somehow manage to be somewhat relatable even as the book continually demonstrated how extreme power alienates them from their own humanity.

Parts of this book reminded me of Charles Stross's Merchant Princes series, especially around the US government attempting to "negotiate" with people who have fantastical power.

I will say also that this book goes to some very dark places, so content warning for abuse and violence and and torture and trauma. To put it one way, when somebody has enough power to read minds, bring people back from the dead, or go back in time to manipulate the past, there's very little escape from their will and manipulation.
