Silver Era Tarot (by Aunia Kahn and Russell J. Moon) will prove as appropriate as it seems.
The card is the Nine of Wands, and I associate it (at least today) with the idea of having to make one last push towards a goal. It's not the kind of goal that means everything is resolved for good - that would be the World for completion, or Judgement for beginning a whole new era, for example. But at least the end is in sight for this particular situation, or so I hope. Big Boy suffered a medical emergency back on the 9th of July, and today he goes in for surgery. It won't solve everything, not by a long chalk, but at least it'll get us back to a manageable status quo.
In today's card, the figure looks to the left, often associated with the past. Her gaze and her stance say it has been a hard road. Still, she stands firm with her wand, and defended by the wands behind her. The colour highlight on this card are the lilac patches on her dress, checkered with black. This returns me to the idea I expressed in talking about the Queen of Cups in this deck (Red Queen), about body wisdom. Here, her wisdom is only partial, it's based just on this situation, rather than being generally applicable. Still, it will hopefully be enough for now.
I am grateful that the end of this situation is in sight.
