The "Serenity-Sons" combo may be the best 5.10 crack climb in the Valley... it is just so, so good. Why anyone would do one without the other, I don't know, but since they are technically two separate routes, they are listed as such.
Sons of Yesterday is the flawless continuation of the climb.
P4: Depending on where you belayed, climb a long pitch of easy terrain past a short steep section of 5.10a thin hands to an airy belay perch on a small tree.
P5: A long pitch of 5.9 in a right-facing corner. Belay at bolts.
P6: Steep 5.9 jamming through a little roof. Belay at bolts.
P7: A wild pitch of 5.9 "walking" along a leaning crack leads to a final stretch of 5.8 fists to an anchor. A sweet pitch.
Begin double-rope rapping from here, sometimes on the route, sometimes just left of it.
Pitch 6 and Pitch 7 can be combined very easily with a 60 meter rope and lots of slings. Done this way, this is the best single pitch of climbing on the entire Serenity/Sons adventure. Save your big cam for the very top of pitch 7.
The last pitch of this climb is absolutely fantastic! Great exposure high of the deck.

Some of the best hand jamming I've done in the Valley. You will want a #3 or 4 cam for the finish after the .75 camalot traverse. I didn't have anything and had to run it out to the anchors. Not bad though. Amazing climb. Try to get there early in the morning as the crowds will be there all day long. You can rap this along with Serenity with one 60m rope, but you will have to use some intermediate rap stations along the way (for example the tree right after the 5.6 section anchors). Combine the last 2 for a super amazing pitch.
I just climbed this last weekend and it seems that the pitch description above is a little off.
The easy linking pitch between Serenity and Sons (officially pitch 1 of Sons) ends in a 2 bolt anchor right before the going gets steep again. From there the next pitch is 120' feet to the second tree which has a pin and bolt anchor ritht above. This pitch is sustained 5.9/10a thin hands to fingers and I felt it was overall harder than anything on Serenity Crack. (All the parties we met agreed with that assessment). From here its hand jam heaven to the top.
The pitch Victor's talking about above is, I think, the best pitch of the day. The slammer hands of the last pitches are fun, and the Serenity pitches are great - but the first real pitch on Sons is long, varied, steep, and sustained. It takes all sorts of pro, all sorts of movement, and makes you draw deep into your quill of techniques for fingerlocks, thin hands, sidepulls, balance moves, crimps, high-steps, a fist or two, and plain old endurance.
A classic 120' of Yosemite climbing.
Just because you get through the feather-lite 3 moves of ".10d" below does not mean that you'll waltz this pitch. My opinion: this is the lead you want to on-site; let your partner have those slammer hands up top.
