You have summoned me. Here I am.
OK, so, you can learn Latin from a good book about it, some self-study volume. In general, these books all get the job done, just look around and see what works best for you.
I'll say, however, that you must understand that Latin doesn't work the way English, French, German, and other languages function: it works like Russian, Finnish, Polish, etc, meaning that you make sense of the words not by the order in the sentence, but by the varying endings of each word. There's a special ending for the noun, one for the verb, one for the object, etc.
This can be a bit daunting as it involves tons of tedious learning by heart. I'll give you a made up example:
>Bob kills John.
This means that Bob kills John, Bob is the subject (the doer), and John is the object (the one who suffers the action).
If I wrote
>John kills Bob.
I'd have the opposite meaning.
Latin works like this (although entirely made-up because I don't speak Latin at all)
>Boba kills Johnum
The -a means subject, the -um means object, and the -s, which we actually got from Latin for third person singulars (he, she, it) means third person singular.
I could write
>Kills Johnum Boba
>Johnum kills Boba
And they all mean the same: Bob kills John, because only Bob has the "mark" of the subject, so in any order, he does the action. For this reason, things can get tricky, although Latin tends to have the verb at the end: "Boba Johnum kills," which is also unusual for us (though not to Germans).
That said, if you are motivated, you can learn enough Latin to get something from it. Plenty of words exist in English that are based on it, and even more in the Latin languages like French, Italian, Portuguese, Spanish, etc, so any knowledge of these will help too, if you have any.
Personally, I'm not too crazy about Latin, from a Christian perspective, as I'd rather know the Greek used in the Gospels, and Aramaic and all that, to know exactly what our Bible says.
I certainly won't discourage you from learning, however. Where I work, we teach Latin, I could ask my workmate about a book in English that teaches Latin if you want.
