You have a lovely minor-grand trine between your Pisces Sun, Pluto for depth, and the Uranus-Neptune conjunction of the mid/late 90s at the apex. These all suggest that your fundamental self is hooked in to the largely social consciousness, which is good for a writer: to be able to speak to others, not just to the self, even while it may come from the self and highly personal experiences. Jupiter also makes a trine to Saturn, suggesting a good sense of balance between ambition and effort for mastery.
You also have a loose stellum in your 5th house, but it receives several challenging aspects from Pluto and Jupiter. These are squares, and to be honest, a chart NEEDS challening aspects, or you get nothing done. The Moon and Mercury in conjunction suggests an ability to verbalize emotion, squaring Pluto suggests being pushed to express it, but perhaps also sometimes coming into conflict with authority (especially female). My son also has a Moon-Pluto square, so I have some idea of how that can play out. If someone tells you "No," how do you respond? If there's an automatic instinctive kick-back, that's typical for this aspect. Depending on how you manage it, it can help you get through the inevitable rejections that come as part of a writing career (any type of writing career, not just fiction). It can either help you keep going or, in the negative expression, lead you to snap back and perhaps burn bridges, or walk away entirely. Just something to keep in mind.
Jupiter also squares the Moon-Mercury combo, which can be good, but may lead to exaggeration at times. Another thing to be aware of. Sometimes less is more. :-D Perhaps the most challenging aspect is the Mars-Saturn conjunction (Saturn can feel like a wet blanket on the bravery and incentive of Mars), squaring Pluto. In short, at times, you may become your own worst enemy, undermining your own efforts either by stifling yourself, or by occasional explosions of temper. Poetry may be one way to channel that energy in a positive way (as Pluto is part of that minor-grand trine).
Squares may present challenges, especially when younger, but are also very energizing, once we learn to handle them. We don't get much done in life without squares, in natal charts, in transits, and in progressions.
