I love this book! The premise of this book is amazing and is basically the fake dating trope (which is done beautifully by the way).
I loved the thought put into the realities of an international relationship on this scale. I know there would probably be even more actual complexities but it just appealed to my overly logical mind that these things had been considered.
I loved the relationships between the characters, particularly the sibling relationships. I felt like it had just the right amount of 'you're mine to bully and heaven help anyone else who tries to hurt you'. How Ellen handled being their mother AND president was also sometimes hilarious and always important. Family was very important in this book.
I thought the characterization was well done. Alex's chaotic impulsiveness (a reflection of Casey's ADHD?) was a contrast to Henry's calm thoughtfulness. Somehow they worked together. I think Henry calms Alex down and Alex helps Henry to let loose a little.
There were subtle hints of a thruple relationship between June, Nora and Pez to add interest. Obviously as Alex's sister we got to understand June's goals and personality a bit more. We got to hear about Bea's backstory and how it contrasted with Henry's experience.
The 'enemies to lovers' and fake dating tropes were just so beautifully combined in this book. I love watching characters get to know one another and learn that the other character might be more complex than they think.
Side note: Boyfriend Material by Alexis Hall also does this trope just as beautifully.
