。
She steered our efforts in the right direction.
Literal
She [topic-は] our efforts [object-を] correct direction [to-に] guided for-us.
導く ('to lead, to guide') is a slightly elevated verb often used metaphorically — guiding people, efforts, or thoughts rather than physical leading (which would be 案内する or 連れて行く). Combined with ~てくれる, the sentence frames the speaker and group as grateful recipients of her guidance — she didn't just guide, she did so for our benefit. The 方向に ('in the direction of') uses に to mark the goal of the guidance.
