This book is fine. I enjoy Marcus's backstory and Phoebe's life as a baby vampire. I really wish they'd kept Jennifer Ikeda as the narrator for this one, because it honestly throws me. Don't get me wrong, I love Saskia Maarleveld, but after almost 75 hours of narration with JI, it's jarring with a new one. I find myself less engaged with the story as a result. Or maybe it's because I find some of the flip/flop storytelling to be not as strong as the first three books.
