In summary, a monostable flip-flop is a flip-flop that has one stable state, which is usually used for timer circuits.

There are RS (set-reset) flip flops, D flip flops, JK flip flops, and maybe a few others that have no useful function or advantage over those already given.
Which one did you have in mind?
As BJT technology has waned over the past couple two or three decades, given over to MOS technology, you may have trouble finding an online BJT equivalent circuit for a flip flop of any sort.

If you go to Google and set it to IMAGES, you can get lots of flip flop circuits.
The common one used as a divide-by-2 is the bistable flip flop.
As you can see, it uses a lot of components and also requires careful adjustment of the bias resistors. After that, it is quite reliable. I know of one that was made in 1972 and is still operating.
These days you would certainly use an integrated circuit.

You could read this description of R-S flip flops:
http://www.hobbyprojects.com/flip_flop/a_transistor_RS_flip_Flop.html
It describes this circuit:
I have several books on digital techniques, but most of them are pretty old and possibly unavailable now. I wouldn't really recommend any of them.
This is a topic where you really need to get into a class and have someone cover it for you in a logical way.
That site above is part of a bigger tutorial on digital devices here:
http://www.hobbyprojects.com/flip_flop.html#flip-flop
It seems quite well done and you might like to start there.

Good grief. I've so long heard flip-flop and bistable flip-flop used synonymously that I don't recall every hearing the term "monostable flip-flop" used-- I had to look it up to see if it really was the same thing as a one shot.
FAQ: Digital Electronics: BJT Flip Flop Circuit Diagram
What is a BJT flip flop circuit diagram?
A BJT (Bipolar Junction Transistor) flip flop circuit diagram is a logic circuit diagram that uses BJT transistors to store and manipulate binary data. It consists of two transistors connected in a feedback loop, with the output of one transistor connected to the input of the other.
How does a BJT flip flop circuit work?
A BJT flip flop circuit works by using the principles of feedback to store and manipulate binary data. When one transistor is turned on, it sends a signal to the other transistor to turn off, and vice versa. This allows the circuit to store and switch between two states, representing the two binary digits 0 and 1.
What are the different types of BJT flip flop circuits?
There are three main types of BJT flip flop circuits: the SR (Set-Reset) flip flop, the D (Data) flip flop, and the JK flip flop. The SR flip flop uses two inputs (S for set and R for reset) to control the output, the D flip flop uses a single data input to control the output, and the JK flip flop uses two inputs (J and K) to control the output and has the additional feature of being able to toggle between states.
What are the advantages of using a BJT flip flop circuit?
Some advantages of using a BJT flip flop circuit include its simplicity, low cost, and reliability. It also has the ability to store and manipulate data without the need for external components, making it useful in a variety of digital applications such as memory, counters, and registers.
What are the limitations of using a BJT flip flop circuit?
One limitation of using a BJT flip flop circuit is its slow speed compared to other types of flip flops such as CMOS (Complementary Metal-Oxide-Semiconductor) flip flops. It also requires a constant power source to maintain its stored data, making it unsuitable for low-power applications.
