Extraterrestrial: The First Sign of Intelligent Life Beyond Earth by Avi Loeb

informative slow-paced

3.5

Interesting read, but the topic and evidence aren't extensive enough to justify a book, so it spends at least half of the book talking about science in general and Mr Loeb's concerns with how it operates.  That is interesting and he writes very engagingly but I felt the title is a bit misleading.
