Three Hitmen and a Baby by Rob Hart
This is the newest in the darkly humorous Assassins Anonymous series. Valencia has to go to LA to save her brother from a gang, so she leaves her young daughter Lucia with 3 of her Assassins Anonymous buddies--Mark, Astrid and Booker--none of whom know what to do with a toddler. When she wakes up sick, they panic and take her to urgent care. But when Astrid and Booker don't even know Lucia's last name (it's Assassins Anonymous, after all), the nurse gets suspicious and calls the cops. Which sets off a hair-raising series of events that sees all of AA members in jeopardy along with Mark's ex Sara and his son Bennett. It's quite the page turner and we learn a lot more about what makes this merry band tick. Hope there's another adventure on the horizon.
