Portalul ingerilor

I thought this book had a totally different tone than the first one. It totally feels like military sci-fi. The pace is kinda slow until half of the book and then it's action-packed till the end. There is a lot of worldbuilding when Takeshi remembers his childhood and the wars he has fought in. There is an interesting group of characters that are put together to fulfill a mission. Alien ruins, old artifacts, soldiers, war, archeology, mental illness.
