This first book in a trilogy about the ancient Carthaginian empire covers the life of the legendary general Hannibal, who famously crossed the Alps with elephants to attack Rome. Of course, Rome eventually destroyed Carthage, and as ever, the victors wrote the history -- so the classical sources didn't leave a ton for the author to draw upon for this historical fiction. That said, the early parts of the book, covering his childhood years as the son of a powerful and wealthy general, are highly effective at portraying the ruling elite of Carthage, and the cosmopolitan nature of his education. He was raised by his father Hamilcar to hate the Roman Empire -- whose appetite for Mediterranean domination inevitably led to conflict with Carthage.
The next part of the book follows the father and son's years conquering territories in Spain. Hannibal emerges as a thoughtful and relatively restrained leader, learning from his father and then taking over when he is killed (the classical sources vary on whether he died in battle or drowned, and Leckie rightly choses to go with the more dramatic option). Navigating a tricky relationship with the venal governor Hasdrubal (portrayed here as a figure of outsized base appetites and shrewd instincts), Hanibal consolidates his power and falls in love with a local princess who becomes an implausibly important supporting character.
As Hannibal and his army make their way across Spain and through to the alps, his monomania overwhelms his humanity, driving him to extreme measures that effectively undercut his army's strength. The book starts to stagger a bit at this point, as the premise of the need of a son to fulfill his father's dream is a thin one at best. And by the time he gets to Italy, it's all somewhat anticlimactic, as the latter twenty years of his life pass by in a scant few pages.
The writing has the feel of mythic figures, rather than actual human characters -- and, as such, it never really clicked for me. There's obviously a ton of research behind it, but it's weighted to delving into the political machinations, military campaigns, and battle tactics. Indeed, the book is full of battles, which are given much attention to detail, from the large scale tactics to zooming in on pitched hand-to-hand combat. It's definitely not for the faint of heart, as there are graphic descriptions of mutilation, torture, rape, and more. All in all, it generally held my interest, but not enough for me to want to seek out the other two books in the Carthage trilogy.
