The Loneliest Girl in the Universe by Lauren James

Romy has daily communication in the form of emails from a NASA employee, Molly and this is pretty much her only social interaction. When Molly contacts Romy to inform her of another mission that will be catching up to her due to it being a higher tech ship. The ship contains J who begins communicating with Romy immediately. Their communications are a few months behind each other so they dont get to read each others replies for ages as it takes so long for the signal to transmit, this was a really nice touch. When there is a war on earth Romy loses communication with Molly and only has J for company, they are both worried about what is happening on Earth and have very little answers. As their communications continue Romy notices a few red flags and begins to question the validity of J and whether he is everything he seems.
Such a unique, thought provoking page turner with such an unforgettable and resilient protagonist. Romy's character growth is ridiculously well done, her constant anxiety and questioning of things made her so believable as well as her trauma surrounding her parents death. I really enjoyed a lot of the mundane details such as her daily life and how she spent her days, it made it all the more interesting to read. Romy's relationship with J was surprising, it was a bit cringe in parts but the idea that they would be the only two people responsible for a new civilisation and only had each other to talk to made everything else that followed more realistic. If you only had each other to relate to then of course you are going to be forced together. It bugged me a little that he was so much older than her (6 years difference) it read as a little creepy at times but did make more sense as the story went on (no spoilers)
The story has quite a few twists and turns and was very tense towards the end. I didnt initially enjoy where the story went as it felt like a 5 star book up until that point but the more ive thought about it the more ive realised that there were few places for the story to go and im now more ok with it.
All in all this is a smartly written sci-fi with thrilling elements as well as coming of age. The mental health representation in here (in my opinion) was SO well done, it explored general anxiety, panic attacks and nightmares which might be triggering for some so i thought id mention it. Romy is badass in her own way, her sense of survival is commendable and shes highly intelligent. Overall I enjoyed it very much, it was so intense at points and i couldnt put it down.
