"Infinite Archive" is the third book in Mur Lafferty's Midsolar Murders scifi mystery series. Mallory Viridian is learning how to deal with being part of an alien hivemind as well as being the mother of a tiny sentient ship, when her book agent tells her that she's going to be the keynote speaker for a mystery convention that is coming to her space station. A giant data-filled ship is bringing the conventioneers as well as a few other surprises. Will Mallory have to solve another murder?
This is a fun space mystery, but you definitely have to have read the previous two books. A recommended purchase for scifi collections.
