I bought the paperback of this in June because I like ice queen and age gap stories. I also liked the cover, it reminded me a little bit of the pulp fiction lesfic covers back in the 50s and 60s like Ann Bannon's Beebo Brinker series. So I finally got around to reading it.
Unfortunately, this was almost a DNF for me. If I hadn't bought it and it had been KU, it would have been returned. It rubbed me the wrong way immediately. Sadie is an American who flies off to Austria to be an au pair for a year. She can't speak German. Thing is, to be an au pair in Austria, you have to provide a certificate of adequate German language skills. You don't have to be fluent, but Sadie can't even string two words together. The only reason she can do her job at all is that the entire family, including the six year old, speak pretty awesome English, even among themselves.
Sadie falls for her ice queen boss, Inga, who is less ice queen and more hurt/damaged wife whose husband ran off with a younger model, leaving her with 3 kids who were bullied at school about it while he plastered his exploits all over Instagram. I'd be a bit standoffish too.
Sadie also manages to get into Germany and France with her US passport without having to deal the any visa waivers or paperwork. She'd be registered as a resident of Austria after 90 days as an au pair, but that's not the same as having an EU passport and being able to travel unhindered over borders. Maybe I am being picky, but it just seemed unrealistic.
I felt the attraction between Sadie and Inga was pretty fast. It doesn't take them too long to end up in bed. I didn't feel I knew the characters deeply enough by this point, so I couldn't connect with their attraction. We do get some backstory, most often in the form of info dumps. Sometimes intense dialogue was broken up with a paragraph of info dumping. That detracted from what the characters were saying and made me skip through to find the dialogue in the prose. Sometimes we got a couple of pages of info dumping. A lot of it could have been cut entirely or shifted to snippets in action tags if absolutely needed. That would have ramped up the tension of a lot of scenes, especially those where Sadie and Inga had differing opinions or where they were exploring their attraction.
Back to the ice queen thing; fair enough, Inga is strict and has a routine, but she easily backs down and seemingly changes her ways very quickly. She does not fight to preserve her facade as a true ice queen would, imo.
Overall, I think this could have done with a fact check and a developmental edit to tighten up the writing, make the characters 3D, and the events more realistic.
