No need to go into the 'plot ' really as so many have done so before, suffice to say that it is dificult to imagine getting annoyed and bored with a woman character whose daughter has gone missing - but Losing You managed this for me.
The term comicbook heroine has been used before by other reviewers and a very perceptive description it is too. Nina is - reasonably- interesting at first, but you've got to wonder about a character/person who lets their teenage daughter sleep out overnight, unpacked, the night before an overseas trip, especially a daughter scatty enough to arrange a surprise birthday party for 11 am ( 11am !) that day , when departure from the house is to be by 1pm. They have a dog too, a Labrador who Nina calls Sludge . I worry about a person who calls animals or children by deliberately ugly names, but be that as it may. The question is really, why does the dog have to be introduced into the story at all, she serves no purpose, and the same can be said for the strange cousin(?) Renata, who arrives ostensibly to take care of said dog and then takes to her bed , or rather Nina's bed, apparently deeply depressed . And then leaves, saying she is "only in your way" ........... I can see why the completely stupid party had to be used to further the plot . But Renata? Sludge?
I can only think that the party, the dog, the cousin and other sundry annoyances are somehow intended to show how our redoubtable heroine can overcome anything in a single bound.
Heaven knows, she does have to overcome stuff. Nobody much likes her it seems, maybe that's why they all came to the party as she was packing for the plane, just to piss her off. Nope, that doesn't figure , mostly they don't even know her, it's only the people who do know her who don't much like her. No idea why all those people - and it is described as dozens -would turn up to such an event. Imagine, a teenager who you barely know invites you to a 11am party for her mother, a woman you don't know at all . "It'll be a surprise for her 40th birthday and we are going to Florida later in the day" says the teenager . "Oh lovely " you say, "We' ll be there, and what is your name again dear? "......
But onward.... once she believes Charlie to be really missing and panic starts to build, she then has to contend with Everybody Else in The World, all of whom are too stupid ,too slow, too disbelieving or too deliberately obstructive to help her . Fortunately Nina is so unimaginably intuitive and clever and unstoppable that she manages the whole thing herself, all the detective work, all the interviews, all the fieldwork, all the denoument, the rescue, the natural justice, everything.
Oh and I forgot , and the the hospital staff are also completely inept and also need Nina-ising, right to the last moment.
The Bad Guy? I hardly remember who it was,so little was created around his character and motive.
