From the perspective of a singing teacher/vocal coach:
Just a month's worth of lessons won't do anyway, that's like thinking 4 piano lessons will set you up with the basics, which they effectively don't - why do people always think this might work with singing, when it seems to be quite clear that it doesn't work with any other instrument?
It absolutely understandable if you can't afford lessons, however in that case, I would steer clear of books as well.
This might sound strange, but if singing, as you say, won't play any part in her musical career, and her singing voice is natural and alright, you might actually do more wrong than good if you try exercises without supervision that you don't really understand. It's not just about copying the right tune in that case, it's also about doing it technically correct, and it will be impossible for you to check this.
If she mainly likes Pop and MT (and I mainly teach contemporary singing techniques, so I'm not adverse to it), she might on the other hand already have bad habits, because depending on when she started to sing along with it, she might have sung songs for adult singers at too young an age (common problem). If that's the case, you won't be able to correct these problems on your own.
It's completely different with someone who already sings and has some understanding of what's going on - in this case, books can be very valuable. I would say though that some basic understanding of how the voice works and WHY you do these exercises, and also what exercises help with any given problem, is essential. You might actually purchase a book which is completely worthless for your daughter, because the exercises in it are not focusing on what she needs. And to find out what she needs, you need someone to tell you what she needs, and that's impossible without hearing her.
Maybe not what you wanted to hear, but my professional opinion. I'm quite sure though that other singers who don't teach might be less adverse to recommending something

I wholeheartedly agree with everything my esteemed colleague says here.
In fact I'll go further and say in the wrong hands books about technique can do more harm than good.
Dugazon and I possess something no book on a shelf can provide, a pair of working eyes and ears and a trained brain to interpret what we see and hear. That is why people pay for music lessons pure and simple.
I can normally hear what is wrong with my back to a pupil and suggest a way to put it right. When I'm facing them and look at them, particularly if I walk around them and observe side on I can normally confirm what my ears are telling me. I very much doubt that Dugazon is any different.
Of course it is much better conducting a lesson facing a pupil as one can do encouraging things like smile at the pupil when they get things right, but there are times (normally when I am accompanying) when that isn't always possible so I swivel on the Piano stool or sit half-way round and demonstrate facing and play side-saddle (works for exercises only) or deliberately use the backing track for a bit so I can watch.
I know music lessons cost money, but they are worth the money (especially singing lessons as the potential for harm is so great)
If anyone wants a reason to justify the cost of getting right first time I have two words - Julie Andrews!
