From the popular Tumblr account of the same name comes a collection of the last messages people received from someone significant in their lives?in a second installment from 15-year-old Emily Trunko.   What if a message you receive today is the last one you will ever get from that person? Would you respond differently, or even at all, if you knew it might be your only chance?   Based on the popular Tumblr account that gained nearly 40,000 followers in less than a month, received national media attention, and doubled in size just one month later, The Last Message Received features a cascade of text messages, social media posts, emails, and more, that contain all kinds of loss, like the end of a friendship, a brutal breakup, a friend's suicide, or the death of a parent.   Featuring exclusive content not available on Tumblr, these messages are full of sudden endings and the type of loss that will inspire readers to reflect on what?s essential in their own lives and the importance of celebrating the people they love every day.
