3.5

first half is stunning, lots of facts that are easy to comprehend

second half is much more biographical which is fine but not what I wanted

I found this book disappointing. Drowning the genuinely interesting information was so much repetition, over- and under- explanation, (fair enough in a way as Lisa doesn't know most of her audience) pages and pages of personal anecdotes right down to describing children making sandcastles on the beach and Lisa's meetings with other scientists and where they enjoyed drinking coffee and why... Many sentences beginning with 'but' (my grammar isn't perfect, but I'm not trying to sell a book). I eventually got fed up with trying to pick and enjoy out the relevant parts and gave up 7/8 of the way through. I really wanted to like it. Probably 2 and a half stars because of the effort taken. It feels like a massive bundle of work notes, personal memoirs and astronomy factlets have been mixed together quite randomly.

This was wonderfully easy to read despite covering a lot of 'big' topics. I enjoyed the personal, humane touch Kaltenegger brings to her scientific writing.
My main takeaway from this book, however, is that we as a society need to instigate a ban on scientists coming up with quirky little acronyms for their projects. The linguistic and mental backflips they are expecting us to do to make these names fit the acronyms are frankly ridiculous.
TRAPPIST? SPECULOOS?
You're taking the piss.
